Error: F1 - About crashes because Package 'textual.widgets' has no class '__wrapped__'

[jeertmans]

Hello!

When trying to add a TUI to my program, see jeertmans/manim-slides#249, the TUI crashes when pressing F1. The issue seems to also occur during tests, see logs.

I have attached the full error traceback below.

Thanks!

Hey @jeertmans, can you confirm whether this is still an issue using trogon==0.6.0?

[jeertmans]

I did bump the package: the TUI works, except for one command present, that fails when selecting it (TypeError: '<' not supported between instances of 'NoneType' and 'NoneType').

See error logs attached. But I guess this is another issue?

I have updated jeertmans/manim-slides#249 to you can checkout it if you want to test locally.

[daneah]

Yep, I think that new error looks suspiciously like #56!

[jeertmans]

Yes instead, I forgot I posted that issue too 😅
