If you have this problem on try the new version of Engine Fixes (https://www.nexusmods.com/skyrimspecialedition/mods/17230); make sure to enable the fix in the ini (it's near the bottom, "SaveGameMaxSize"). I won't rule out the possibility of multiple different issues causing crash-on-save but this one specifically fixes SevereArtisan's problem.

Pretty sure the problem is entirely "uncompressed save data > 64 MB" and the lz4 compression code is crashing due to running out of room in a buffer. I will try to patch the size to 128MB or something like that when I get a chance.

Hey guys. SevereArtisan gave me a crash log for his crash-on-save and in his case the game is crashing in LZ4 compression code while writing the save. Skyrim SE compresses parts of its save games - note that LE _doesnt_ do this at all. If you add the following to your ini: [saveGame] uiCompression=0 It will disable compression. No idea if this will allow the game to save but it's probably worth a shot for the people experiencing this.

I verified it fixed it on my test setup that replicates it pretty much as soon as I start playing, but its pretty hard to test all the cases.

Hey y'all, The root cause of this issue is that SSE's file loader is outright breaking under certain circumstances. This causes it to fail to actually read save files, which reports them as corrupted (essentially it thinks they're 0 bytes). This is also what breaks everything else - the game is trying to load those things on the fly (NPC dialogue etc) and failing to read anything. Basically: It's not a specific script's fault and its not the fault of string count or anything in your save game. Don't have a fix (yet?) but it will obviously require skse plugin. Edit: file open failed due to too many files open, the reason it works again after restarting is the game is fresh.
