Import error with no debug info

Running this version of Mac OS Catalina and everytime I import a deck I get this error

I have tried imports on anki 2.1.48 and 2.1.49, disabling all add-ons except special fields, and trying multiple different deck files.

Can you reproduce the problem with all add-ons disabled? If not, you’ll need to report the issue to the special fields author.

Interestingly enough updates worked on this ankiweb account with no add-ons enabled, but when switching to another account special fields continued to work
