MX432 will not connect to my Windows 10 anymore


I've had this printer for almost a year and it has connected fine, although my girlfriend was never able to connect it to her laptop. Now, recently, it stopped working on my laptop and only works on hers, which she got a few months ago. I just spent about 45 minutes trying to fix it, but nothing seems to do anything. I uninstalled it after trying a number of other things, and now it won't reinstall. It just keeps saying the printer is not connected/detected. I restarted my laptop and tried again after realizing I needed to restart it. I tried connecting it by USB as well as wireless. I updated the wireless network info. It's connected to the Xfinity. My laptop detects the wireless network. I looked under "hardware" info and it said error "Code 45." I looked that up and there's no info anywhere about error code 45. There's no other info about what the error is. Nothing is wrong with my USB ports.

Also, this issue started right after I changed out the black ink. I've tried reinstalling that as well.

Please help.
I recently updated Windows and that's the only thing I can think of that would cause this issue.
