Cannot drag survey elements in creator

Hello,

I am using asp core .net 8 as my environment.

Originally was using version 1.12.26 of the creator package however, I have recently upgraded to 2.0.2.

I have 0 errors in my browser console when on the creator page.

Here is how I have my creator setup in javascript and html

In my cshtml file I have the following resources

Code
<link href="https://unpkg.com/survey-core@2.0.2/survey-core.min.css" type="text/css" rel="stylesheet">
    <script type="text/javascript" src="https://unpkg.com/survey-core@2.0.2/survey.core.min.js"></script>
    <script type="text/javascript" src="https://unpkg.com/survey-js-ui@2.0.2/survey-js-ui.min.js"></script>
    <script src="https://unpkg.com/survey-core@2.0.2/themes/index.min.js"></script>
    <script src="https://unpkg.com/survey-creator-core@2.0.2/themes/index.min.js"></script>
    <link href="https://unpkg.com/survey-creator-core@2.0.2/survey-creator-core.min.css" type="text/css" rel="stylesheet">
    <script src="https://unpkg.com/survey-creator-core@2.0.2/survey-creator-core.min.js"></script>
    <script src="https://unpkg.com/survey-creator-js@2.0.2/survey-creator-js.min.js"></script>

    <script src="https://unpkg.com/ace-builds/src-min-noconflict/ace.js" type="text/javascript"></script>
    <script src="https://unpkg.com/ace-builds/src-min-noconflict/ext-searchbox.js" type="text/javascript"></script>

and then I have the creator rendering like this

Code
<div class="col-md-12 mt-1">
    <div class="form-row align-items-center p-0 m-0 m-1">
        <div class="col-md-12 p-0 m-0">
            <div id="surveyCreator" style="height: 100vh;"></div>
        </div>
    </div>
</div>

Then for my JavaScript file

Code
const creatorOptions = {
    showThemeTab: true
};

const creator = new SurveyCreator.SurveyCreator(creatorOptions);

then I use custom questions that are created by building JSON through C# and add them to the toolbox like this

JavaScript
creator.toolbox.defineCategories([
    {
        category: "Custom Dropdown Questions",
        items: [
            "activityCategoryDropdown",
            "yesNoDropdown",
            "campusesDropdown",
            "programStatusDropdown",
            "objectCodesDropdown",
            "districtsDropdown",
            "regionsDropdown",
            "fundingSourceDropdown",
            "diStudentGroupCategoriesDropdown",
            "studentUiDropdown",
            "visionGoalSummaryTypeDropdown",
            "activeProgramListDropdown",
            "baselineYearDropdown",
            "activeDiStudentGroupsDropdown",
            "studentUiDropdownInPlan"
            ]
    },
    {
        category: "Custom Checkbox Questions",
        items: [
            "activeDiStudentGroupsCheckbox",
            "diStudentGroupsInPlanCheckbox"
        ]
    },
    {
        category: "Custom Matrix Questions",
        items: [
            "objectCodeAndDollarAmountMatrix",
            "fundingCategoriesMatrix",
            "activeStudentDiGroupsMatrix",
            "objectCodesInPlanMatrix",
            "fundingCategoriesInPlanMatrix",
            "diStudentGroupsInPlanMatrix",
            "activityCategories",
            "visionGoalsInPlanMatrix",
            "sharedProgramFundingMatrix"
        ]
    },
    {
        category: "Custom Panel Questions",
        items: [
            "visionGoalsPanel",
            "studentDiGroupsPanel"
        ]
    },
    {
        category: "Choice-Based Questions",
        items: [
            "dropdown",
            "checkbox",
            "radiogroup",
            "tagbox",
            "imagepicker"
        ]
    },
    {
        category: "Text Input Questions",
        items: [
            "text",
            // Override the display title
            { name: "comment", title: "Multi-Line Input" },
            "multipletext"
        ]
    },
    {
        category: "Read-Only Elements",
        items: [
            "image",
            "html",
            // Override the display title
            { name: "expression", title: "Expression" }
        ]
    },
    {
        category: "Matrices",
        items: [
            "matrix",
            "matrixdropdown",
            "matrixdynamic"
        ]
    },
    {
        category: "Panels",
        items: [
            "panel",
            "paneldynamic"
        ]
    }
], true)

creator.toolbox.allowExpandMultipleCategories = true;
creator.toolbox.showCategoryTitles = true;
creator.toolbox.forceCompact = false;

This is how I am rendering the creator in JavaScript

Code
document.addEventListener("DOMContentLoaded", function () {
    creator.render(document.getElementById("surveyCreator"));
});

Please not that the creator was working fine before I upgraded to 1.12.26 and then did not get resolved as I upgraded to 2.0.2

The interesting thing I I found is that even on SurveyJS demos I was not able to drag any elements in the creator.

Thank you

I also found with version 2.0.2 that the creator is loading in very slowly once again this is something I noticed on the SurveyJS demos as well.

Hello,
Thank you for the update.
I tried to apply your code in a sample, however, I didn't get any mentioned issues (View Plunker).

I'm afraid that I need to get a reproducible demo to reproduce the issue on my end. I would appreciate it if you create a simplified demo and send it to us for research.

Thank you
