Kontakt not completely loading NKIs (GGD, Roomsound etc), slow load times

Hello- first post here. Apologize if this violates any kind of community etiquette but this is a show-stopper issue and I've exhausted all resources and have no answer.

Kontakt was working yesterday. Today I pull up Cubase 12 and start another session, open up Kontakt and try to pull up an instance of GGD M&M (for example) and it takes forever to load and is stuck on their stock backdrop and a "LOADING" screen. They take forever to load and then show up with incomplete GUIs and do not work. Every library I own is doing this and it had put everything I'm doing to a complete halt.

I've reset, rescanned, rebooted. Everything.

I'm not sure what else to do. Has anyone else experienced this issue before- and if so, how did you resolve it? Apologies for the picture orientation idfk how to get it to show up upright.

I'm on Kontakt Full 6.7.1

Standalone Kontakt player seems to work fine, apparently...

Appreciate any help/advice.
