Ich kann mich den Kommentaren nur anschließen. Ich würde empfehlen, sich erstmal mit dem Installieren von AUR-Paketen vertraut zu machen. Folgende Tutorials sind zwar auf englisch, kann man sich aber auch per deepl übersetzen lassen, wenn nötig:
TL:DR
DISCLAIMER: AUR packages are user produced content. Any use of the provided files is at your own risk.
sudo pacman-mirrors -aS unstable
sudo pacman -Syu base-devel
When you sync your system any CUSTOM package may cease to function without warning OR your system may cease to function due to a CUSTOM package - therefore one must remove all CUSTOM packages before an issue can be validated as related to Manjaro.
custom packages - unsupported - you are on your own!

What is AUR?
The Arch User Repository is an online repository, managed by the Arch community rather than the Arch packagers.
AUR differs from the Manjaro repositories by multiple, important key points:
AUR does not contain packages, but PKGBUILD s. See below for details.
AUR is not managed by Manjaro.
There is thus no official support for AUR packages.
Package compatibility is not ensured for all points in time. See below for details.
