We are using Appium to test our multi-platform app. (Windows, Android, iOS). This App is written using C# in .Net 8 with MVVMCross.
However, since about month or 2 ago, our App crashes on start up on iOS when the Appium xcuitest WebDriverAgent is running.
Looking into the logs and console, it's because the app is taking longer then 19 seconds to start up. If the WebDriverAgent is not running, the app is starting in less then a second and it working fine.
This seems related to the exact .Net version, as this started happening when.net 8.0.303 was updated to .Net 8.0.401. But any attempt to downgrade to .Net 8.0.303 doesn't seem to make it work again, meaning either our downgrade isn't working or it's something else that was updated around the same time.
We also realized that the ios workload has received an update. We were on 8.0.300 (we believe, could have been 8.0.100 as well) and now it's 8.0.401. We also can't downgrade that on our build server to test unfortunately.
We updated appium and it's drivers was part of the attempts to resolve this issue. It also stopped working with an older version so I don't think Appium directly is responsible for this not working anymore.
Edit2:
Does anyone have any idea what this could be?

This issue is because the long-time starting on iOS device, right? Is there any change in the iOS version between two months ago and now? Did you update the iOS version on your device? And would you mind sharing the AppDelegate class so that I can determine what you did when the app launch?
