    <description>&lt;P&gt;I downloaded &lt;STRONG&gt;Maya2020 trial (for business user + single user)&lt;/STRONG&gt; to my &lt;STRONG&gt;macbook pro(16-inch, 2019, macOS Big Sur ver 11.1)&lt;/STRONG&gt;. It worked well at that time and I shut down the macbook as normal. However, when I used the macbook today and launched the Maya app again, it popped out stack trace error message. I have found a similar issue &lt;A href="https://forums.autodesk.com/t5/installation-licensing/maya-2019-start-up-problem/td-p/9537452" target="_blank" rel="noopener"&gt;here&lt;/A&gt;&amp;nbsp;but its solution was about versioning.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I have re-installed a few times but it didn't work. I have also reset the maya preference &lt;A href="https://knowledge.autodesk.com/support/maya/troubleshooting/caas/sfdcarticles/sfdcarticles/Reset-Maya-to-Default.html" target="_blank" rel="noopener"&gt;as mentioned&lt;/A&gt;&amp;nbsp;and still not working. Here below is the error message and hope that someone could help:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;STRONG&gt;Stack Trace:&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;Cannot find procedure "shaderBallRendererMenuUpdate".&lt;/P&gt;&lt;P&gt;Start of trace: (command window: line 1).&lt;/P&gt;&lt;P&gt;shaderBallRendererMenuUpdate (command window: line 1).&lt;/P&gt;&lt;P&gt;=================================================&lt;/P&gt;&lt;P&gt;loadPlugin renderSetup;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// renderSetup //&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// Error: line 1: Cannot find procedure "MTsetToggleMenuItem". //&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// Error: file: /Applications/Autodesk/maya2020/Maya.app/Contents/scripts/muscle/cMuscle.mel line 505: menu: Object 'mainRigDeformationsMenu' not found. //&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// AbcExport v1.0 using Alembic 1.7.5 (built Feb 7 2018 13:51:52)&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// AbcImport v1.0 using Alembic 1.7.5 (built Feb 7 2018 13:51:52)&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// Error: file: /Applications/Autodesk/maya2020/Maya.app/Contents/scripts/others/addSelectTypeItem.mel line 101: Cannot find procedure "updateSelectTypeItemState". //&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// Error: file: /Applications/Autodesk/maya2020/Maya.app/Contents/scripts/startup/autoLoadPlugin.mel line 35: initializePlugin function failed (gpuCache) //&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// Error: line 1: initializePlugin function failed (gpuCache) //&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// Warning: file: /Users/kayilam/Library/Preferences/Autodesk/maya/2020/prefs/filePathEditorRegistryPrefs.mel line 4: filePathEditor: Attribute 'aiImage.filename' is invalid or is not designated 'usedAsFilename'. //&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// Warning: file: /Users/kayilam/Library/Preferences/Autodesk/maya/2020/prefs/filePathEditorRegistryPrefs.mel line 5: filePathEditor: Attribute 'aiPhotometricLight.aiFilename' is invalid or is not designated 'usedAsFilename'. //&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// Warning: file: /Users/kayilam/Library/Preferences/Autodesk/maya/2020/prefs/filePathEditorRegistryPrefs.mel line 6: filePathEditor: Attribute 'aiStandIn.dso' is invalid or is not designated 'usedAsFilename'. //&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// Warning: file: /Users/kayilam/Library/Preferences/Autodesk/maya/2020/prefs/filePathEditorRegistryPrefs.mel line 7: filePathEditor: Attribute 'aiVolume.filename' is invalid or is not designated 'usedAsFilename'. //&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// Error: file: /Applications/Autodesk/maya2020/Maya.app/Contents/scripts/startup/ModObjectsMenu.mel line 56: setParent: Object 'mainModifyMenu' not found. //&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;// Error: Failed to register Initialize Maya Modify menu.

      <description>&lt;P&gt;Problem is solved! I found the solution &lt;A href="https://forums.autodesk.com/t5/maya-forum/maya2020-macos-catalina-10-15-2-application-crashes/m-p/9304272/highlight/true#M78962" target="_blank" rel="noopener"&gt;here&lt;/A&gt;.&lt;/P&gt;&lt;P&gt;It is about something like the &lt;STRONG&gt;permission of accessibility in Security &amp;amp; Privacy&lt;/STRONG&gt;. Actually, the app asked me about accessibility permission previously but I didn't set it at that time. I didn't know it will cause trouble like this. Hope this will be fine in the future.&lt;/P&gt;</description>
