This bug is a graphical glitch or error

Describe the issue

Whenever OpenRCT2 starts, I get this message in a popup "Failed to load language file! Your installation may be damaged". From the program's standard out, I see that it is attempting to load the en-GB localization.

I've also tried with the latest stable release of OpenRCT2 and that has the exact same failure with the same error message while attempting to load the en-GB localization files.

ERROR[/usr/src/debug/openrct2-git/openrct2-git/src/openrct2/localisation/LanguagePack.cpp:62 (FromFile)]: Unable to open /usr/bin/data/language/en-GB.txt: Unable to open '/usr/bin/data/language/en-GB.txt'

FATAL[/usr/src/debug/openrct2-git/openrct2-git/src/openrct2/Context.cpp:438 (Initialise)]: Failed to open fallback language: Unable to open language 8

Potentially related, in directory /usr/bin/data/language/ there is only localization data for the development build of OpenLoco that I also have installed: en-GB.yml and en-US.yml

Steps to reproduce

1. Use the openrct2 binary to set the game files location
2. Run openrct2. It will show the popup window mentioned and then will not proceed any further.

No response

Start with the reported failures at src/openrct2/localisation/LanguagePack.cpp:62 and src/openrct2/Context.cpp:431 and 438, then reproduce the launch after setting the game files location. Inspect why the installation looks for /usr/bin/data/language/en-GB.txt; done means OpenRCT2 starts without the language-file popup and loads the configured or fallback language.
