How do I avoid The high OS version validation error ?

My (very) old xmarin.forms UWP project suddenly isn’t accepted by the Windows App Certification Kit 10.0.22000.194.

I get the errors below

Error Found: The high OS version validation detected the following errors:
I’m not checking OS version in my code (I don’t know if the xamarin framework is doing that). The only thing I’m doing is checking if it is on mobile. I have tried to disable (comment out e.t.c.), but that makes no change.

Error Found: The crashes and hangs test detected the following errors:
I have noticed that when I run the app in the debugger it always ends with

The program ‘[17940] xxx.exe’ has exited with code 1 (0x1).

I can’t find out why it ends with that. How can I find the cause ?

Based on the error message, your app will crash on a higher version of windows, you could test on other versions of the device on your side or go through your code to check if you are using some API that only works on a specific version without checking the OS version.
