Bug/Issue Crash on Entering Skull Mines

So I've got a few mods installed, and since last night they worked well with everything. I only had one hiccup with Sam's 2-heart event where no matter what option I picked, it kept asking me to pick a response again...so I just skipped the cutscene.

Anyway, I went into the Skull Mines no problem last night with all the mods installed, but now when I try to enter just the initial cave from the desert, my game crashes. I've got a log here from SMAPI, but I don't know how much help it'll be. It looks like it's saying that the Skull Key isn't present in my wallet, and is crashing because I've already been in the mines. I could be completely wrong though, I'm not very good at reading/understanding error logs or codes lol.

If I have to load an earlier save, I've got some on backup that I can use, but would rather not. Any help would be much appreciated!

I'd like to go ahead and close this thread. I went and deleted all my mods, verified integrity of the game, and am currently re-installing one-by-one and testing to see if I can find the issue (if there even is one anymore).
