I recently run projects and it worked, but today it fails:

This is Xojo 2020r2.1 with my current plugin.

adhoc signature is there for debug build!?
Some plugins load, even with this code signature error!?
Anyway, the problem seems to be differently as I get runtime error reported when using AVFoundation plugin here.
Maybe someone can check case 63122 - Plugin fails to load in iOS app.
