I primarily play on the old 1.12.2 version of minecraft. Today when I tried to start the game through the launcher, the launcher closed as normal, but the game window did not appear. There was no crash log, or anything. When I restarted the launcher and attempted to relaunch, it said that minecraft was already running. I've uninstalled a couple mods I was running, but the issue is still appearing. I've also tried to launch several other versions, including 1.12.1, 1.12, and 1.11.2, but all of these had the same issue. Any version after this, (I've tested 1.13 and 1.16.3) seems to work normally.
