Hello, I Just upgraded to GNUCash 3.6-1 from 3.5-1. In 3.5-1 all system/menu items are in French as expected, with 3.6-1 everything is in English. Reverting back to 3.5-1 I get interface back in French. MacOs 10.14.5 (18F132) MacBook Pro (Retina, 13-inch, Late 2012)
Please attach a trace file, see https://wiki.gnucash.org/wiki/Tracefile.
I've got the same issue but with Italian translation. If I start the app from Terminal, I've got the following warning message: (process:6569): gnc.gui-WARNING **: 15:31:44.760: [mac_set_languages()] Language list: it:it_IT The locale defined in the environment isn't supported. Falling back to the 'C' (US English) locale
Can one of you upload a tracefile, please?

I've got the same issue with the Croatian translation.
Fixed in git for GnuCash 3.7. Unfortunately the error is after the environment file is read so there's no work-around.
