Hello I am having some issues.

[ImUncreative]

So a long time ago I got forge for Minecraft 1.19.2 and it worked well, well today I decided to get forge for 1.16.5 due to a mod that I wanted only being available for 1.16.5 and I thought that it would appear separate when choosing what version of Minecraft you want to play but it replaced the 1.19.2 forge. Now whenever I play forge my game always crashes and I can't even reach Minecraft's main menu or anything. It also says "Exit Code 1" if anybody knows how to fix this issue could you please tell me? I also had mods installed on 1.19.2 forge so could that be the problem? Do I need to re-download 1.19.2 forge and get rid of the mods? If you can help me please do.

As 1.16.5 is not supported on this forum, I'll give you a simple answer. If you are loading up a version, the mods folder must only contain mods for that version. You can have multiple mods folders if you have different game directories for each profile configuration, but otherwise that must be it.
