I was using the beta release "replaymod-1.15.2-2.3.0-b1" and the game runs fine But when using the Latest version The game crashes for me.

• I am using
  

• What did actually happen? "the game crashed before launching"

• the log (The Crash Log)

Hope you can fix this in the next release

According to screenshot and crash log, you're trying to use the MC 1.12 version of the RM on 1.15.2, the crash is also what I would expect from that combination.

i feel stupid now
