Monitor won't attach after deattach

[Broken-V]

Hi,

Today I've downloaded the most recent version of little big mouse, then when accedentally pressing detach, I couldn't attach it back, I have looked here for answers and went to my monitor config looking there. The button to put my 2nd monitor as active again is grayed out. So then I tried un-installing LBM and also no luck.
Any ways to fix this, that I have not already discribed?

Go to windows display settings (right click on the desktop) select the detached monitor and choose extend in the dropdown menu.

Every time I use the extend it doesn't work and defaults it back to disconnected. Uninstalling and reinstalling doesn't work either. Tried looking for a config and it didn't appear where people said it'd be.
