Keynote has a problem with my font cache and is running slow

Is there a reason why Keynote can't seem to load fonts? Every time I go to the font selection dropdown Keynote practically crashes. I do have a lot of additional fonts installed in my system but it's ridiculous how keynote can't seem to handle it but every other application can. What am I missing? Is there a setting that would help keynote load font faces better? I have an Apple M1 Max with 64 gb of memory...this really shouldn't be a problem.
