Glyphs3 crashing and won't open after installing Plugin

I have experienced similar issue:
After installing some plug-ins, and launching GlyphApp again, a message pops up: “an installed plug-in requires Python 3.”
After installing modules > Python, and launching GlyphApp again, then it does not open.
v 3.0.2 (3052)

What version of MacOS do you have?

Are you sure you are pressing the right keys during startup? Option is sometimes labeled ‘Alt’ or has the symbol ⌥. And the Shift key has the outlined arrow ⇧ on it.

Working on 10.14.6

Just to be sure: Glyphs starts but the plugin manager, will not open? Can you check the if you find anything there (search for ‘Glyphs’) to get rid of the other messages.

Glyphs does not start. A pop up message " Glyph closed unexpectedly". Therefore, nothing can be opened.
It happened after installing modules > Python, and launching GlyphApp again.
v 3.0.2 (3052) Mac OS 10.14.6
Find enclosed the report.

Can you send the log as a .txt file. The text is messed up in the .pdf.

uploading .txt files is not accepted.
Do you want me to copy and paste the whole content?

Then zip it. (26.1 KB)


I can tell for sure that it is a reporter plugin that causes the crash.

Thanks, Georg!
I will try to find out which plugin is, and avoid installing it.

Please send me a zip of the repo folder of that plugin.

@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

I’m getting no access to many plugins; also after removing and re-installing:
The following alerts show one after the other:

then no Python version shows in the preferences panel:

Those are my Mac spec.

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

It will only do so after a restart.

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

It is not listed here !

Check under Modules.
