Glyphs3 crashing and won't open after installing Plugin

[BastardaType]

@GeorgSeifert and @Andreu we had the same problem, however the problem was solved after we changed the Python version to 3.8.2 – we have set this here:

Glyphs > Preferences > Addons > Python Version

All plugins are working now. Thanks to @federicoparra

The following alerts show one after the other:

Those are my Mac spec.

When you install Python through the Plugin Manager, give it enough time to install.

@Avantino

then no Python version shows in the preferences panel:

It will only do so after a restart.

Is it supposed to show in the Plug-ins Manager ?

It is not listed here !
