Found out that I didn't update something or changed something accidentally. The datapack I've linked here was actually a release build and not the development build I used. I've done this that way, because something like that was happening in 1.16.3, but someone told me that it was fixed, so the issue wouldn't occur. It was some kind of typo / mistake that console didn't notice until entering the biome, what resulted in game freeze.
Custom worldgen using custom biomes can freeze world generation until exiting or task-killing (in case if the world won't leave "saving world" screen).
Issue occur when generating a lot of terrain in short time (can't tell if it won't occur when we'll generate a lot of terrain, but slowly)
Console error output is preceded by this warning:

Issue with previously "frozen" chunks will resolve after reentering the world
