Thank you for that. I am still stuck.

I have had some success not having the error immediately opening the settings, by running a repair and a reset of Studio 2021

Repairing your installation of Trados Studio (sdl.com)     

Instead, I got the same error later while working and opening the project settings, apparently randomly!

In addition to that when I try to check my project TM settings I could open, I got another issue!

I closed the case after I could get support and install properly the WorldServer Compatibility Pack 16.9.1783.

Thanks Paul
