Provide at least the following information

• Minecraft version - Minecraft 1.21
• Mod version and malilib version - Sakura-Ryoko-Litematica-Mod-Fabric-1.21(v0.17.9999-sakura.1) & Sakura-Ryoko-MaLiLib-Fabric-1.21 (v0.18.9999-sakura.1)
• A clear description of the issue - I was deleting some blocks of a pasted schematics (in singleplayer, falt world) with the area editor. After a minute deleting different areas the game crashed. Now im not able to enter any singleplayer world. Not even a new one. But im able to play on multiplayer. Pretty strange.
  I tried to enter the singleplayer world without the mods, it went succesfully.
  I tried to delete the world and enter a new, it failed.
  I tried to search for same litematica cache in the minecraft files but i couldnt find them.
  I tried to use litematica in a multiplayer server, it went succesfully.

Im pasting to this post a txt with the crash report. Im pretty sure yo can find more info about the problem than me =)

Update your mods using Github

Use:

https://github.com/sakura-ryoko/malilib/releases
https://github.com/sakura-ryoko/litematica/releases

I do not name my files like that.

Based on the file names I think these are probably from some shitty mod repost scam site like 9minecraft.

This is what it gives me atm:
