elfprince if it's the same result when you launch program from terminal, then it's not the dock.
if a single Brave window launches from terminal and three from the dock, I'm still not convinced it's the Dock but I don't know what it means.
they (@BloodFeastMan @BuzzPCSOS ) are likely right, it seems like hardware/mouse.
If sudo eopkg check
came back clean then..
I can't even find a word grouping that can bring me a single instance of your problem.
batch command corruption? dongle failure (happened to me when I went back wired) but I think you are wired. something also says driver to me. mouse settings fubard somehow? edit: unplug clean blow out mouse jack hole?
mystery right now for sure.
I will see what I can read. that's a PITA to have all those windows open.
