Launcher won't open

Won't open at all. I click on it, it says it's updating, not even 30 seconds later, it hasn't loaded at all and a new window says how it cant be updated. I've tried repairing it and deleting and reinstalling it.

If it helps I last opened it with Forge, the latest (1,19,2021) recommended download. It was lagging after I had it open all ngiht so I closed it through the X on the top, instead of save quit, quit .
