You can always file. It works or it does not. Generally does not hurt you to try. The closest thing to a downside is if you are accepted, the base period just got locked in. If you are rejected, you can always try again if your situation changes.
Based on what you have said it is not impossible you will get some level of UI benefits. The key is the quality of the termination (generally "you are fired" versus "I quit), and what your reported income is for the base period and what you are still making now. Assuming UI likes the quality of the termination, current income reduces the amount of the benefit, but does not make you ineligible.
