Oops mb meant to put yes for other mods involved, it stops happening when I remove all mods except these 3 and their dependancies.

Could you possibly do some more tests with subset of your mods to find which one is conflicting?

FerriteCore, ModernFix and Sodium would be some suspects.

Modernfix looks like it was responsible as it stopped happening when I removed it, could it be a config problem or something?

This happens because the ModernFix's mixin.perf.dynamic_resources option is enabled. I've just tested it.
This option greatly speeds up the loading of my Minecraft instances, and also reduces memory usage.
Thus, I'm hoping for some kind of workaround to fix this.

Yes, disabling that option is a temporary solution until I'm able to provide a proper fix.

Fixed by updating Puzzles Lib to v21.0.20.
