A detailed walkthrough of the error, its code path and all known details is as follows:
---------------------------------------------------------------------------------------`

The solution was to throw the chisel into lava

did you upgrade from chisel 1.20 to 1.21?

no i just installed the 1.21 version, i didnt used it before

Hmm is there anything you did to the chisel before this happened?

Actually what item did you leave in the chisel

I think it was cobbled deepslate
