@Rhazeem - I have exactly the same issue after Patch 7 and the subsequent hotfix. Also GoG, and also no mods (I've never installed any mods). I went through almost exactly the same troubleshooting steps that you did, and "thought" I had figured it out when I installed the new BG3 Toolkit via GoG and it then let me start the game, but I'm guessing it just cleared out relevant local files because even though I could start a new game, it now fails again when I try to load back in.
By any chance are you also running Honour Mode on your new save that is crashing?
I'm also wondering... and maybe this is a clue. After I installed the Toolkit and it let me in the first time, I had to set all of my keybinds again. I don't recall ever having to do that before when starting a new game. Also when I started the new game, I could see all my old save files... so "maybe" it isn't everything under that local Balders Gate 3 folder... maybe it is just one or a few of the config files. I'm going to see if I can't figure out which by deleting/renaming some and trying a bit more...
Edit: I think I figured it out: it is a problem with changed player profiles, and specifically custom keybinds.
Try renaming just this file: %LocalAppData%\Larian Studios\Baldur's Gate 3\PlayerProfiles\playerprofile8.lsf -> to playerprofile8BAK.lsf.
My game will consistently start after I do this. It just means we have to re-accept the license agreement and nudity setting, and optionally re-apply custom keybinds.
If I DON'T change keybinds, I can now restart as much as I like without problems. It is only when I change a keybind that the game crashes on load.
(My middle mouse button is combined into my scroll wheel, which is hard for me to use for Camera Rotate. I always remap it to a side button, X2.)
Hopefully this trick will work for you as well. It is still annoying, but way better than losing the save game!
Edit2: OK, so now I think it is more than just potentially that one file. I was fine at first with it. I was only changing the keybind after loading a save game.
I then changed the keybind BEFORE loading a save game, and exited straight out of the game. This caused the game to crash on load again, even after renaming the playerprofile8.lsf file.
Now I'm wondering if there is something else going on, maybe with service calls to GoG. Heck, I don't know. Frustrating.
