i've recently experienced this issue. here's my 2 solutions;

Which mod do you want to use? Which version is that mod? Well, the version of the mods you use DOES depend. If your forge is v1.16.2, then you should ONLY have 1.16.2 mods in your mod folder, with the outdated mods removed from the folder.

if you still need help, please lmk.
