@johannesnoordanus Try installing from the main development branch maybe, we don't support 3.13 yet.

Pillow should work with 3.13 alpha 6. The change that caused this problem only appeared in 3.13 beta 1. It is fixed by #8050. On July 1, Pillow 10.4.0 is scheduled to be released, which should include that, and also include Python 3.13 beta wheels.

However, Pillow will not officially support Python 3.13 until Pillow 11.0.0 on October 15, because that will be the first release after Python 3.13 final is released.
