Appdesigner apps won't run

Whenever I try and run an appdesigner app I get this error. I can't run anything what do I do?

Error: File: AppManagementService.m Line: 65 Column: 63

Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To construct

matrices, use brackets instead of parentheses.

Scott - what is line 65 of AppManagementService? From the error

Error: File: AppManagementService.m Line: 65 Column: 63

[Scott Gorman]

I don't know I don't have access to it as far as I am aware. It is not something I am using. It just appears when I try and run anything in appdesigner.

Undefined variable "AppManagementService" or class "AppManagementService.m"

Scott - do you get this error when creating a new app? Or does this just occur for your current app?

[Mohammad Sami]

The error itself is likely to be in a callback from your app code.

You should set a debug pointer in the constructor and step by step to see where the error originate from.

[Scott Gorman]

It occurs for all apps I have. If I create a new app it doesn't appear but as soon as I save and run that new app I get the same error.

Sounds like you may have corrupted: appdesigner.internal.service.AppManagementService. Probably worth contacting tech support. At least in R2020a, line 54 of that file is a comment.

Thank you I have just submitted a report.
