When I updated my steam deck Prism Minecraft launcher no longer found a java install.
I used the command java --version and got back bash: java: command not found
Seeing that java must have been unintalled somehow with the update I decided to reinstall java using sudo pacman -S jre17-openjdk jre8-openjdk and got back

“warning: jre17-openjdk-17.0.5.u1-1 is up to date — reinstalling” seems to indicate that java is still installed but nothing I have tried can find it. I need to find it so I can put a path to it in the prism launcher.
Theres a lot going on here. Any help would be appricated for the Linux noob.
This is a programming site, but somehow, I don’t think you’re trying to program anything. You might have gotten lost on the way to Steam support. Log into Steam. Find the tech support link. Contact them.
Steam OS uses an immutable root partition. You should keep it that way. Manually installing to your home folder could be a solution.
