Can not validate or distribute App with QuickLook Plugin

After switching to BigSur and a MacBook Air with M1 I am not able to validate or distribute my archived app that contains a QuickLook Plugin generator for my own file format.
Xcode 12.3 crashes during validation process.
If I remove the QuickLook generator from my app bundle everything works fine. A fresh rebuild of the generator on my Apple Silicon Macbook air did not help.

On my older MacBook Pro running Catalina and Xcode 12.2 validation and distribution are successful.
I suspect some kind of signing problem but automatic signing is activated.

I've already integrated the new QuickLook extension API but would like to keep the old generator to support older macOS versions.

What am I doing wrong?

Well, that’s not good. You should file a bug about that. If you can attach the archive that triggers the failure, that’d be grand.

Please post your bug number, just for the record.
