IDE Crash since using Windows 11 and Version 2021 R 3.1

Hi everyone,
since i use Windows 11 on my new Laptop i’m going crazy with IDE crashes every second or third time debugging my project.

I know that their could be issues with several antivirus software, but i already tested it after deactivating my software (HP Wolf Security). Still the same problem.

Any other experiences with crashing IDE on a Windows 11 machine?


Run the IDE from a CMD.exe window. There should be additional info when the IDE crashes.

Thanks Greg, i will try this to get more information…

I had the next crash and now i can read in the event log that there was an error in the XojoGUIFramework64.

@Sascha_S experienced something like this, 0xc0000005 in XojoGUIFramework64.dll (but Win10), interestingly both of you were using a German localization of the OS.

“German localization of the OS.”
as test/workaround you could change os to English

“new Laptop”
so os and graphics are up to date?

Some OS’s are Single Language only and can’t change. Unless you are talking about not changing the language but just the International Settings (time, numbers, money, etc)

Yes, all drivers and Windows are updated…

I guess I have the same problem (Xojo 2022r1.1 under Windows 10 and 11 with Swiss German).

They said there that they possibly found the culprit and maybe the next version does not present such bug anymore. Soon they will do some tests in some problematic environments. Interestingly, all those I’ve noticed are using German or some Alemannic dialect, but in the past we had bugs affecting some specific locales / time zones, as



That comes from only running unit tests on a system set up for en-us

It’s not very cost-effective to run a non-US system just for unit tests that run once a day.

VMs exist for this. You can can run 3, 5, 10 localized tests in parallel, not testing at all a software target to the international market should be something I would be shamed to expose.


Well since I don’t work for Xojo any more, I was just stating a general fact. I don’t actually know what is don’t inside Xojo any more.
