Package Project and Cooking Dont work?

hello,
so randomly out of the blue packaging or cooking seem to stop working?
every time i choose either option immediatly in a split second it shows the “Packaging Complete!” or “Cooking Complete!”
with nothing being saved, pakaged or cooked or anything at all.
im wondering if anyone experienced this or theres just a simple option i gotta tick to fix this.
this happens with all projects btw new or old.
also when looking at the output log. it doesn’t show any red text indicating that theres something wrong.
the version i use is 4.18.3

the things i tried so far:
reinstalling UE4.
deleting the unreal folders in %appdata
deleting regeitry entreis.
installing other versions of UE4
restarting windows.

thanks.
sorry for my english.
