App Designer 2024b broken

I was fine using AD in 2023b but now with 2024b I'm finding weird things. Asking if anyone else has seen these issues. (I also reported to ML Help)

Save As to change the file name to a new version pops up an error about another program opening the file (non existant) and then crashes when reopening. Always at 10% it stops reloading for more time that I want to wait. Usually loads in less than a minute, I let this run for 10.

It seems to have randomly corrupted my column widths that were set long ago. Changing with to auto with values that don't work on the GUI screen. I had this working 10 versions ago and now it decides to corrupt my settings?

I'm also having problems with AD in 2024b. It worked fine in 2024a so something has changed. This is an app I have been working on for years with no issues like this. AD itself appears to initialize correctly but when I select my app I get an incomplete and partially grayed out screen. This is as far as it gets.

The GUI never manifests on the Design View tab. I can see the code on the Code View tab but most of the control buttons are grayed out. The screen then locks up such that the only way to close it is via the Task Manager, i.e. kill it.

I was hoping the first update would correct this but it didn't.

I've got mine working now. I'm not sure why. Some of the callbacks were randomly disconnected from their components so I had to go back and fix those.

I'd sure like to hear from ML staff as to if this is a known issue that is either fixed or in the works for being fixed.

After working with the MatLab staff my issue was resolved. The fix was to create a blank app in AppDesigner and save it. Then open my app from the open menu on the toolstrip. This appears to have reset a couple of internal files and corrected the issue. After that my file opened and functioned normally.

A decent work around. But hopefully they can fix it so one can create a new version and it opens and work normally.
