When I start Minecraft 1.12.2 forge, minecraft doesn't open
Do you get an error message?
If necessary, restart your PC.
No I don't get it and I have already 3 times
Try reinstalling Forge.
Also make sure that the mods fit and are also in the correct folder.
Maybe it helps to reinstall Minecraft.
Nice day!
I've already done everything
Can you start Vanilla, ie "normal" Minecraft?
Yes and forge without mods
Then it's apparently due to the mods. What kind of mods are they?
Okay, thanks for the picture.
I know it's annoying and very cumbersome, but I see it as the solution if you sort out each mod individually and see if it works.
Since the logs don't help you, this is the only way from my point of view.
Maybe also write which mod was to blame.
OK
