Launcher doesn't open on Arch Linux

Same thing in endeavour os (arch based distro) with KDE Plasma as WM

I have the same issue, but I made a script that starts on login that automatically deletes the webcache2 folder for me after exit:

#!/bin/bash

# Path to the webcache2 folder
WEBCACHE2_DIR="$HOME/.minecraft/webcache2"

echo "Script started"

while true; do
    # Check if the Minecraft Launcher process is running
    if pgrep -f "$HOME/.minecraft/launcher/minecraft-launcher" > /dev/null; then
        echo "Minecraft launcher is running"

        # Wait until Minecraft launcher is no longer running
        while pgrep -f "$HOME/.minecraft/launcher/minecraft-launcher" > /dev/null; do
            sleep 1
        done
        
        echo "Minecraft launcher closed"

        # Delete the webcache2 folder after launcher exits
        rm -rf "$WEBCACHE2_DIR"
        echo "webcache2 folder deleted."
    fi

    # Sleep for a short time before checking again
    sleep 2
done

That's kinda smart, nice

A more “permanent” solution is to delete the plasma-browser-integration package, it’s also in the KDE Bugs Tracker (see Bug #501866)
