Trados 2021 Errors Creating Translation Memory

Greetings,

I have the latest version of Trados 2021 and whenever I try to create a new translation memory (either via project setup or in the TM tab), an Error box pops up and the app hangs. There's no text on the Error dialog - it's whited out. I've tried uninstalling and reinstalling the app, renaming the directories in Appdata\roaming to no avail. Anyone have any ideas?
