The usual Manjaro updates plus pay attention to the dependency hell that has been happening for the past 2 or so months. You will have to probably use the terminal and update with either
pamac update or
sudo pacman -Syu and type “y” to replace the packages with the newer named-ones, when asked.
The latest dependency hell is about the JDK/JRE packages. You can read more here. What seems to fix it is to do:
pacman -R -dd jre-openjdk pacman -R -dd jre-openjdk-headless pacman -Syu jdk-openjdk
One by one.
