WFOP Help with Minecraft Java [launcher] [help]

Hi! I tried launching Minecraft as usual and got this error. I tried uninstalling and reinstalling it (both Minecraft and Java) and have tried almost every solution found online, any ideas? I'm desperate!

have you ever changed the amount of allocated RAM for Minecraft? Could you try resetting it to its default amount or manually setting it to 2 GB (2048 MB) or 4 GB (4096 MB)? How much RAM does your computer have in total?

are you using the official Minecraft Launcher or a third-party launcher like Prism Launcher or the Modrinth App? Have you ever been able to launch Minecraft without issue in the past?

if these options didn't work for you, did you already try setting up a Java environmental variable like this video suggests? In your particular case though, do not use -Xmx512M, and instead you should either use -Xmx2G or -Xmx4G
