Minecraft forge crashes exit code 0?

I have a problem i have been looking for the perfect mod and version for days and have now installed a few but an exclamation mark is always displayed in the launcher for the forge version and the game crashes immediately after starting with exit code 0 What can I do?

The exclamation point is just a warning that the version has been modified by a third party.

For the exit code:

Go to Settings in the launcher and check the box for Open output protocol as soon as games are started.

If the "Minecraft game output" window opens when starting, remove the check mark from info. There's (possibly) a different exit code below.

If not, download the ADWCleaner:
