Intellij IDEA not loading (most of the time) on Linux

Intellij IDEA only sometimes manages to load correctly on Arch Linux. What I mean by this, is that the window manages to start every time, but the UI itself isn't loading most times.

When launching IDEA via the command line I get this output:

OpenJDK 64-Bit Server VM warning: Archived non-system classes are disabled because the java.system.class.loader property is specified (value = "com.intellij.util.lang.PathClassLoader"). To use archived non-system classes, this property must not be set
CompileCommand: exclude com/intellij/openapi/vfs/impl/FilePartNodeRoot.trieDescend bool exclude = true

My system is running on Arch Linux with Hyprland and XWayland on the latest Nvidia proprietary drivers and an AMD x64 CPU.

I have these plugins installed:

• Atom Material Icons
• glsl-plugin-idea
• IdeaVim
• intellij-rainbow-brackets-lite
• Material Theme UI Lite

I don't think these are the problem though, as even without them being installed the problem sill occures. I am not very knowledgeable about IDEA though, so I don't know if there is maybe some cache I forgot to clear when reinstalling, that loaded them.

These are the directories I cleared:

• ~/.local/share/JetBrains/IdeaIC2023.1
• ~/.cache/JetBrains/IdeaIC2023.1

I reinstalled 2 times, without any success. Even though the first launch after every reinstall was successful, which leads me to believe it has something to do with caching.

I installed IDEA from the AUR, to be specific intellij-idea-community-edition version 4:2023.1.2-1. I tried intellij-idea-community-edition-git, but it coundn't satisfy the dependency java8-openjfx. Here is the exact Output I got after running : 'paru -S java8-openjfx'
