Export not working after the first time


I’m using Glyphs 2.5.1 on macOS 10.14.1.
When I try to export a font, it only work the first time. If I try to export again I get this error message:

(in english: Operation could not be completed. No more information is available about the problem.)

I have to restart Glyphs to be able to export again.

Can you try the latest cutting edge versions (activate it in Preferences > Updates) if it is fixed there? If not, can you send me the .glyphs file?

Thanks for the quick answer !

I just installed 2.5.2 and the problem persists.
I’m sending you the .glyphs file by email.

And what macOS do you have?

I’m running macOS Mojave 10.14.1
