Exporting do not finish on Glyphs Mini

I am trying to export font with more than 12,000 glyphs with Glyphs Mini, but It will not end for more than 1 hour with the display being “Exporting…”.
During the export process, the CPU usage rate is 100%.
About 1,000 glyphs font exported successfully.

Also exporting the same 12,000 glyph’s .glyphs file with Glyphs (not Mini), exporting completed in about 10 seconds.

The version of Glyphs Mini is 2.0.1.

Sorry for my poor English.
Any advice would be appreciated.

Can you send me the .glyphs file?

I sent you a .glyphs file to (email address removed)
please confirm.

I got your email. Thanks.
