Server Error whenever I'm upload to my personal gallery

Hey everyone. Having this same issue, I get the same "server error" popup everybody mentioned whenever I try to upload to gallery or even save to my own library. I've tried taking out the Tray folder, taking out most mods (because I installed some big ones yesterday and thought that might be why I'm having this issue, tried with all mods disabled, tried room by room (most didn't save, some did, none had any mods and I removed all crafted and half-crafted objects and photographs so it wouldn't detect any "cc"). I also tried saving an empty lot with just one of the new sales shelves from B&H, same problem.

I'm worried that at any moment I might have any other issue and lose my household and build that have so many hours behind them. Literally irreplaceable, with all the family photographs and everything.

If it helps, it all takes forever to load to. When I click save lot from build mode, the window immediately opens but takes forever to load and stop being completely greyed out. Then the pictures take forever to load too, and once I click save or upload it takes forever until the error pops up too. So it does kinda seem like a server error, to be honest. No idea.

Game also crashes in some of the attempts. Not even a "not responding" pop up, just blink and it's just fine and loading and then blink and it's closed. No signs.

I have NOT had this issue before today, nothing to do with any game updates for me appparently.

I'm on PC, I have like 87GB of CAS CC and a decent amount of mods, but like I said, took out all the new ones and tried that, and I tried a lot of these things with mods disabled too. The biggest of the new mods I installed yesterday are Lumpinou's RPO (almost all modules), LGBTQIA; adeepindigo's Divergent Sims and Healthcare Redux; and Pandasama's Childbirth mod, amongst a bunch of other smaller mods.
