UE4 character rotation error.

I know it may sound stupid. I don’t know exactly what happened, but it appeared after I tried to implement some YouTube aim offset tutorial. Now my character rotates only 180 degrees and in a very strange way. I pressed A and D, but my character turned only left. Does anyone know what the problem could be?

Hey there @kiran789! Welcome to the community! It kind of looks like you may have disabled this setting in your camera’s spring arm. Is this currently disabled?

Yes! Exactly! Thank you SOOOO much!!!
