Hello everyone!

I'm facing problem with our integration with Trados after upgrading Trados from version 17.0.3.11695 to 17.2.8.18668.

Our application doesn't start properly and produce following log:

INFO 2024-01-09 09:42:54 – Starting application

INFO 2024-01-09 09:42:56 – Initializing project server

After some research I've found that the method Sdl.Desktop.Platform.PluginManagement.StudioPluginManager.Resolve[T]() itself is causing error without apparent reason.
I've created simple project that only runs this one line and it gives the same result:

Do you have any advice on how to fix it?

Cheers,
