TouchGFX 4.21.3 crashes with ERROR TouchGFXDesigner.App: Object reference not set to an instance of an object

[MCerv.2]

Hi, hoping someone can help with the following issue I'm experiencing. I understand that my setup might fall outside of the supported enviroment but I thought about posting the question anyway.

I'm running TouchGFX 4.21.3 on a VM with Windows 11 ARM in a Macbook Pro M1 Max. TouchGFX access the project files through a map network drive.

Everything works except every time I save the project or compile I get a message saying that the project files was externally modified which isn't the case it's the app itself who is modifying it. Normally pressing Yes keeps things working

When modifying anything on the Texts Tab I also get the same error but indicating that the text.xml file was modified here pressing Yes or No will cause the app to crash with the following message: Object reference not set to an instance of an object.

I've attached the logs from the application in case they provide more details, is there any way to increase the logs verbosity?

What options can I try? Do you think having the source files in a mapped drive could be causing the issue?

Hello MCerv.2,

Hard to say... that's for sure an uncommon setup. We'll need more time to investigate this issue. I can't promise any fast resolution for it.

I understand that, but unfortunately that is the only way I can run TouchGFX Designer right now. Most other ST tool have cross platform support except GFX so it's quite unfortunate. is there any way to increase the logging verbosity so I can try to troubleshoot the issue?

It also happens to me an a plain Windows11. I have noticed that this happens when there are changes on the project, in my case because of repository changes, while Designer is open. I can not tell exactly what order of operations produce this error.

Thanks for your input, mine project is also inside a git repository but i haven't seen it fail because of the repository changes but rather when the app itself is making changes to the files which doesn't make sense

I suspect this issue could be related to the "file already exists" error when a project is created on a network drive:
