Found a solution after messing around with this again, the .ifs files are actually just the .arc files. Replacing "dance_shock_arrow_v0.arc" with a copy from the old 2018 rip of the game worked for me, knock on wood I have not run into any other issues yet and played for about an hour and it never crashed.
As you have mentioned numerous times in the thread, the torrent version is the way to go and would have avoided this entire issue. I just can't currently torrent and the mega download was my only option.
I could also very likely run into other corrupt files that the game may not have tried accessing yet in my hour of play who knows, fingers crossed it just keeps working.
