Multiterm (Studio 2017) freezing/crashing when trying to add new term. No error messages. Reinstalled, did not sole the problem.

Multiterm (Studio 2017) freezing/crashing when trying to add new term, then stopped working. There were no error messages, it just kept freezing every time I wanted to add a new term, then it stopped launching altogether (and still no error messages). I reinstalled it and I am having the exact same problem. I have given my antivirus and firewall additional permissions in case that could be the problem, but it does not seem to solve anything. Anyone experiencing the same or who can help?

Thanks!
