Suddenly unable to connect to X-controller

Good Evening All.

I’ve been successfully using my Xcarve for several weeks now. Unfortunately, tonight when I went to use it, I was unable to connect at all.

I was on GRBL 1.1F
Unable to connect using Easel, UGCS, Picsender.

Easel Reports “Com3 access is denied”:

The machine itself is kind of “stuttering” or something everytime I try to connect with something.

I have tried with two different computers at this point, same behavior.

I’ve searched through the forum, but I am unable to find anything that has fixed it

I have unplugged, restarted and tried different USB ports. I have also made sure the E-stop is all the way up, both lights are on.

Any ideas? What are the actual settings supposed to be within the port in device manager? (windows 10)
