Fatal error generating a pyo3_runtime.PanicException in Anki 2.1.55

When learning my Greek vocabulary set, entering a certain (wrong) solution, πιάνω τσακώνομαι, reproducibly crashes Anki with the following error message:

A fatal error occurred, and Anki must close.

A fix for this is coming in the next update, thanks to @Rumo.


Super and thank you, very glad to hear!
