I am dealing with the same problem.

macOS Big Sur (version 11.5.2)
Python 3.8.9
pip 22.0
erdpy 1.0.24

@Kaco92 I guess that the version of rustc you and I have is rustc 1.60.0-nightly as it is mentioned in your output above:

INFO:myprocess:Successful run. Output:
rustc 1.60.0-nightly (e0a55f449 2022-01-28)

I got some Hint from elrond dev gus ( Try reinstall rust by comand 'erdpy deps install rust --overwrite ' )

[bluedragon1120]

I solved this issue like this.
I used "mxpy contract build --no-wasm-opt" instead of "mxpy contract build".
Plz try to again with this.
