[thecooltechguy]

im also getting the same error

[Penlect]

Which version of Cython was used here?

[mxmilkiib]

3.0.3

[androidnisse]

Trying to build this on Solus with cython 3.0.10 gets a build error as well.

[Penlect]

I bumped Cython to version 3 when building wheels with the latest version of cibuildwheel, and the package appears to build correctly. Hopefully, this resolves the issue.
