Question Package cache was invalidated...

I'm new to Unity, and I've run into some issues. I havent done much except follow some tutorials for the 2D platformer microgame. This message appeared on my project right before Unity crashed, and I was wondering if the two were related? Thanks!


The package cache was invalidated and rebuilt because the following immutable asset(s) were unexpectedly altered:
