Trados 2021 not starting

Hi,

We’re running into a problem when starting SDL Trados Studio 2021 Professional (Network SN) on one of our PCs. The program hangs on “Executing ‘Setup Wizard’”. After a while, we get the message “Het doel van een aanroep heeft een uitzondering veroorzaakt” (“System.Reflection.TargetInvocationException” according to the log), sometimes followed by an error message about the “Splash screen”.
We’ve tried uninstalling and reinstalling Trados and removing all temp files, but the issue persists.

Many thanks for your help.
