Im unsure if this is just a random crash which is not even related to the mod, but I'll report it anyways. the Crash report mentions Mine Cells as you can see.

Please see if setting experimentalMusicLooping to false in the minecells-client.json5 config file fixes it 😁
Can you also give some details about when and how this happens? Does it happen when you enter some dimension, when you launch the game, or when exactly?

I'll try to find a solution for this anyway - thank you for the report!

Edit: closed by a missclick, oops

I'll be sure to try that tomorrow, although I did update 2 mods, and after downgrading them I didnt crash. The mods were CreativeCore and Dynamic Fps, its probably the second. Do I let you know once I figure it out?

Edit: It happens when entering any world, the world loads, and then freezes and after some time it crashes. But it is not caused by Mine Cells bc after disabling it, it mentioned another mod in the tracktrace.
