I have no idea how to continue. Do you have a solution for this?

What we've found out is, that this issue is only appearing on windows but working on mac OS.

my python version is 3.9.13

Thank you very much!

tried to install magenta but receive errors

what I already tried and didn't work:

• reinstall all 3 packages

• downgrade versions of those packages

• the same with cmake and wheel package

• install windows sdk

• test it on another device
