When I launch the minecraft launcher, the loading screen of "Mojang" pops up and loads until it is at 95% and stays there. I have waiting like hours for it to fully load, but the bar does not move an inch. I used to run the game just fine, now it doesn't seem to work. My last play with the game was when I was trying to use mods for Java Edition. I took a break from the game for a few days and came back to it only to see this problem. Please help.
