Almost 2,000 Asset Errors?!?!?

PLEASE HELP. I have been trying to fix this problem for a week but I cannot find any solution to this problem nor the problem itself but 1 old reddit thread that has no answer. When I validate the assets and dependencies on my Fortnite map I get around 1,700+ Asset errors. It was only around 900 at first but when I uninstalled and then reinstalled both Fortnite and UEFN to try to fix it, it almost doubled in errors. When I try to migrate the map into a different blank map, UEFN usually crashed around 40%. I am new to UEFN and map creating in general so I have no idea what I am doing wrong.

Does this show when you do this?

Because that generates errors even for me but I can just ignore them

Or does it show when you validate from these buttons
