Forge installed but not running

[DividedFox]

hey everyone! I have been having trouble trying to get forge 1.12.2 to run lately. it has no problems installing, but when I try to run it in the Minecraft launcher, it doesn't open. there is no crash report, but the game never loads. when I try and open up the launcher, it says the game is already running for a bit and then lets me try and run it again. I have tried uninstalling Minecraft and uninstalling forge and the forge installer. none of it worked. I don't know what else to try. I hope you guys have some ideas!
