Well i have to say that rpghuds have all problems with 1.19.3:
I made a fresh install of ittemsadder and RPGHuds.
Problems:
No working or showing: compas/quiver/arrow target
Problem showing money using placeholder api.

Following commands where performed:
iazip
iareload
iatexture
Still the same. No errors in logs.
Those plugins are installed:

All up to date.

Configuration of itemsadder
Configuration of rpghuds:
Remember is a fresh install without the defaultpacl
Now with the default pack installed:
https://github.com/ItemsAdder/DefaultPack/releases/tag/2.0.8

Still happend the same, adding coin/money not showing overlapped. I know that i can fix the position of the coin icon using the documentation in the wiki. But in this case is the same, not showing the RPG HUDS.
I have to said that i performed the iazip, iareload, and iatexture all.
Additional: LightApi where failing at the start, not loading. To fix this i enabled the Compatibility mode to True, then Light api loaded okey.
enable-compatibility-mode: true
no errors in logs. Sorry about my english.
