SSB3DS unmapped read32 error and Citra freezes

Issue:
I was playing classic mode, and I won a battle. Then Citra shows “game”, then after the screen fades to white Citra just freezes and crashes. This also happens if I lose the game. If it matters, it was game 2 of ZSS’ classic mode route.
Also, if the CPU or I plays as Mario or Shulk, the game just loads forever while continuing to show tips (and Citra doesn’t crash).

Here’s some issues I found with your log that might help.

This sounds like a corrupted update or DLC install. You ought to remove them then redump from your 3DS again. Make sure godmode9 is updated and that you have enough free space on your Nintendo 3DS’s SD card.

You need to browse manually to the title folder then inside both 0004000e (update) and 0004008c (DLC) delete the folder with the game’s ID. You can see the game’s ID by checking the cheats menu (Emulation->Cheats while game is running).
Close Citra before you delete those folders.

Unmapped memory read/write errors can also be caused by corrupted update, even base game but hopefully you only need to redump the update.

I did that, and now it’s giving me this error:

HW.GPU <Error> video_core/command_processor.cpp:WriteUniformFloatReg:84: Invalid vertex shader float uniform index 127

The good news is that Mario and Shulk work now!
Also the full log file is too big to upload on here and freezes my browser if I try on pastebin.

I turned off mods and now it isn’t giving me the error, I just have to find out which character is causing the problem.
