Error when trying to quick add a term to the termbase through Trados

I created and started using a TermBase through SDL Trados 2021 today, and then suddenly every time I tried to quick add a term pair it freezed for a bit and then came up with a message "Errors occurred whilst displaying the terms from (termbase directory) using source English. Please try reorganizing the termbase from the Termbase Management view. If this fails to resolve the problem please contact SDL support."

I went on MultiTerm and reorganized the file, but the error persists. Besides this, it seems to even manage to add the term besides the error message and the termbase continues working normally, the main issue is that then every time I try to add a new term it will crash like that for some 20 seconds and then give this error message, which is quite disruptive to my workflow. I tried restarting both Trados and TermBase before and after reorganizing, but nothing seems to fix this.
