I always over plan things. I'll plan encounters appropriate to level. I'll plan NPCs. I'll plan dungeon themes. But I won't plan a dungeon themed encounter unless I know they're heading into that dungeon because it's where we ended the last session.
To put it another way: I never plan so specifically that a thing can't be moved to another place unless I'm positive it's coming next.
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.

There will still be the ability to do this, I don't know the exact mechanic, but it was asked and answered when Paizo was doing their Livestreams regarding the remaster
The week has been crazy and I got no physical games played, only BGA or mobile/tablet versions of games
Way back when I delivered pizzas, if someone ordered anchovies, we'd put the pepper number on the pizza and they got the rest of the can in a little container on the side because nobody wanted to smell them in the store until they eventually got thrown out
I don't know if you're on BoardgameArena, but Targi available to play there without a paid membership
Finishing up Troubles in Otari and we'll transition over to Agents of Edgewatch from there. I've been trying to set it up by mentioning the big event in Absalom and I'll have Vandy recommend the PCs to a friend who is looking for new recruits.
