Why is my Y rotation stuck at 180?

When attempting to rotate an asset, my Y rotation value has gotten stuck at 180 and turned blue. It appears to be locked, and won’t allow me to rotate anything else in my scene - when I type, it will only rotate the original asset. I can still rotate objects manually, but it’s rather inefficient and inaccurate.

Any suggestions?

Turned blue how? If you can post a screenshot someone might know whats up.
