Monster Hunter 4U crashing on startup

Issue:
I have a .3ds file I decrypt and then load into my Citra games folder, Citra says the file is good and displays: 3DS1191 - “Monster Hunter 4 Ultimate (USA)-decrypted.3ds” with the proper thumbnail. I click the game to start it says loading for a moment then goes black then the program crashes and closes itself. Log is attached. I’m new to Citra so thanks for your help.

Please properly redump your game using our dumping guides. Decrypting on your PC often leads to corrupted ROMs. Refer to our game dumping guides:

Dumping Game Cartridges
Dumping Installed Titles

Make sure your GM9 is up to date and that you have enough free storage space available on your SD-Card to perform the dump.
