Since the 1.17.34 update I get the attached errors sometimes when I launch Minecraft. This happens on both of my PCs.
Steps to reproduce
Turn on content log file and content log GUI.
Disable any non-vanilla packs in global resources.
Close Minecraft.
Reopen Minecraft.
Expected result
No errors on startup.
Observed result
Exactly 80 "Invalid lang file format" errors.

Is it still an issue in the latest version?
