No text in main menu when game locale is RU

## Issue
I have my game language set as Russian, and I have no text in the main menu of the game (see image 1), and partially in the FAF lobby (see image 2). However, the tooltips still work and the text in English is still present (see image 3). The issue disappears, when the game language is set to English. Also the issue is not present in the Windows version. Unable to confirm the issue on the vanilla Steam version of the game, because it simply does not run with or without the recommended launch parameters.
## Attempted fixes
I've tried installing fonts from `Supreme Commander Forged Alliance/fonts`, tried putting them into `~/.fonts`, into `C:\Windows\Fonts` on FAF's wineprefix and on Steam's wineprefix for SC:FA (`steamapps/compatdata/9420/pfx`). Also tried renaming the `Supreme Commander Forged Alliance/fonts` to something else, as I saw that suggested on ProtonDB.
## Specs
Ubuntu 24.04, system locale `ru-RU`, `language-pack-en` installed
Wine 9.14 from the `winehq-devel` package through their apt source
Official Steam (from a `.deb` file)
