Unity 2022 UWP development build error

Hello guys,

I tried to build a UWP project with MRTK and OpenXR configurations and it seems that if I check the development build + script debugging options in the build menu I get this error:

I get this error even if I try to build an empty project (tried with Unity 2022.1.0a8 and 2022.1.0a12).

Stdout:
Error: IL2CPP error for method 'System.Boolean System.Runtime.InteropServices.WindowsRuntime.IBindableIteratorToIEnumeratorAdapter::System.Collections.IEnumerator.MoveNext()' in assembly '__Generated'
System.InvalidOperationException: Error while processing debug information. This often indicates that debug information in a .pdb or .mdb file is not correct.
Check the debug information corresponding to the assembly '__Generated'.

I don’t recall which bug report this is, so I can’t give a status update, sorry!

I believe it’s this one: Unity Issue Tracker - [UWP] Project fails to build when Development Build and Script Debugging options are ticked

I’m running against this wall on Unity 2021.2.7f1, [EDITED] @JoshPeterson I’m using UWP methods (e.g. Storage) not in Unity’s APIs so can’t debug with the editor, the app is crashing when I build but logs don’t show much info to progress the app, what do I use until the update lands?

thanks a bunch everyone for the update :slight_smile:

I can confirm this.
Unity 2021.2.7 can’t build an UWP build with “Script Debugging” enabled if a line of code like this one is used:

private static readonly List<StorageFile> lastOpenFiles = new List<StorageFile>();

It seems something with the List-implementation is wrong.

All I know is that it worked with Unity 2020.3.20 - please fix it.
