Launching MHS3 on Steam Deck with REF Nightly 01371 gets it stuck on a black screen

[GuyOnASofa]

Describe the bug
When I try to launch Monster Hunter Stories 3 on Steam Deck, it gets stuck on a black screen, and doesn't load the REF window. Taking out the dinput8.dll file lets it launch correctly.

Upload logs and any crash dumps

re2_framework_log.txt

(Attempting to upload the raw txt file here resulted in an unspecified error, and uploading it anywhere else gave an error that the file was empty/had 0 bytes, so I copy pasted the text in the file into an online notepad website and made a new txt file to get around it. Sorry if this causes any issues.)

Identify the REFramework version
REF Nightly 01371

To Reproduce
Steps to reproduce the behavior:

1. put the dinput8.dll file in the game's folder
2. Launch the game
3. Game gets stuck on black screen

Expected behavior
Game launches normally with REFramework working

Screenshots
Photos of my game folder in case it helps:

Steam Deck/Linux (please complete the following information):

• Proton version Default (No compatibility tools forces)

Additional context
I have also tried adjusting the Launch Options to be "WINEDLLOVERRIDES="dinput8.dll=n,b" %command%" with no changes.
