Who told you to do this? Where’d you get the info to use the AUR for everything?
In any case, please read through the following threads. Make your life in Arch Linux less complicated by following what actually experienced users recommend.
Install apps in this order once they are available:
Official Repos > AUR/Chaotic-AUR > Direct binary from app website > Flatpak > Snap
The second and third are interchangeable depending on the app, but if you decide to add and use the Chaotic-AUR, do not put it ahead of the Official Repos.
A direct binary file could be an AppImage, zipped folder, etc.
