Nightly problem (EDIT: solved?)

EDIT: It's the next morning, and despite this happening multiple times in a row last night, I can't replicate the issue in a video this morning. I'm thinking it may have just been a memory issue? Anyways, I rescind the fact that it's a problem for now. I'll keep an eye on what actually causes it.

So, I'm trying out 4.5, and I've found that whenever I try to use a mordent (the pralltriller is fine) Musescore 4.5 crashes. I know it's not a fully finalized version, just thought this might be worth mentioning.
