I want to use this resources pack on my 1.16.5 instance. When Dynamic Resources is off, the process of changing res pack runs smoothly. But I then enabled Dynamic Resources, the game will crash during launching.

I tried to remove any mods but ModernFix, this problem is still there.
Crah report: crash-2023-09-13_17.10.53-client.txt

I also tried starting a new instance, with Dynamic Resources pre-configured to on. It will report "unable to reload resources" when trying to change res pack. It didnt crash, but the res pack will not be loaded.
log:
latest(dynres_on).log
latest(dynres_off).log

This is because the resource pack contains a file with an invalid name (models/block/pressure_plate_down x.json). Resource pack files should not contain spaces. Manually removing the file from the pack fixes the issue.
