I just found that if I use L or R to switch weapons while the screen is shrinking from using exit, there's a frame where this will cause the game to hard lock.

...just lost a run 2:30 ahead after Exit split to it... as if battling RNG wasn't bad enough already, lol.

I play on emulator, and have been able to lock the game from multiple save files throughout the game in a similar fashion, so it wasn't a one time occurrence. Has anyone else had this problem, and specifically, has anyone experienced this on console? Thanks!

I've had this happen as well but only once. I'm not sure if it happens consistently, but I've worked it into my muscle memory to only change weapons on the fade in after an exit transition just in case.
