Hello, community,

at my company, we updated to SR1 of Trados Studio 2022 a few days ago. Since then, we are having problems with the Verification. Specifically,

1. Verfication takes extremely long (for a project with multiple small files it ran for over an hour, maybe nearing even 2 hours)
2. Verification frequently returns errors such as these
   1. Stacktrace 1 (code below)
   2. Stacktrace 2 (code below)

Any ideas for how to fix this? We think it's got something to do with forbidden terms (of which we have not many in our termbase, but even if we uncheck this option in the Verification settings, the process does not work properly).

Stacktrace 1:
