So I posted a comment about this a while ago, but despite attempting every solution recommended, the problem is still happening, where in certain scenes (such as the hypnotist, the fourth temple fish section, and the telescope puzzle in the vagrant camp) I am given an error message and the game crashes. I have tried removing the read-only attribute from this game multiple times, but it always reverts to read only, and I do not know how to change this. Idk if anyone can help, but I'd appreciate it if there's some solution I'm missing.
On windows 11, for clarity, error message will be attached.

I'm stumped as well. So far none of these solutions have helped, and every time I tried the command prompt, it gave a message that the format of the command was somehow incorrect, though I've used the command as suggested on every site I've seen.
The apology is not necessary, I know this isn't really your fault, whatever problem is here, it seems to be an obscure one.
I wanted to pop in here and say, after basically giving up on this problem for months, writing it off as a lost cause, I just on a whim ran the game as administrator today, decided to try out one of the scenes that had previously caused the crash...
Ran the scene 3 times, no problem.
Assuming this holds, I am almost annoyed by how simple that was to fix.
Still, thank you for all your help, and for the great game.
