I almost bet the GM found a map they thought looked cool and is just throwing stuff at you to fight because it’s faster and easier than coming up with storylines and characters with motivations. I get it, we GMs get busy with life and stuff too, but if you’ve been doing this for a while, there’s always a reserve of characters or stories that you made but didn’t use which can be pulled into the current game. With a new GM, they may not have that luxury.

All that said, the best course of action seems to be the thing you’ve already concluded: talk to the GM and the group. Maybe let someone else try being GM if it’s just the case of the current one being busy. As others have said, running a prewritten campaign is just fine, especially in Pathfinder. Heck, you can even buy many of them as foundry modules with music, maps and handouts all ready.
