So I didn't touch Minecraft for about a month and my launcher updated to 2.1.17784 and I was able to play once but after adding one texture pack the issue started, I already deleted and reinstalled MC, tried playing different versions of MC, deleted the downloaded texture pack, tried different java versions and nothing.
Every idea that comes to mind doesn't work.
I would like to avoid needing to download anything but I will if I have to.
My pc specs just in case.
AMD Ryzen 5 2600x overclocked to 4.2Ghz
Rx 580 8GBVram overclocked core at 1365Mhz and memory at 2155Mhz
This is a bug with the launcher; based on your screenshot you should be able to click on "start anyway"; the reports don't reveal much as to a cause but I suspect that some specific system configuration is causing it (I don't get this error):
