Projector just stopped working

Hi, I bought this Elephas Projector from Amazon a few months back. I haven’t had any issues with connecting it to my iPhone with my charger cable. Normally, Once I hook my phone to the cable it will begin to charge my phone (that’s how I know it’s successfully connected) and then begins to “screen mirroring”. Today I went to go plug it in and use it like I normally do, except this time when I plugged my iPhone in. Instead of it “screen mirroring” it just showed a black or blank screen but continued to charge the phone as if it was still connected. I have unplugged, powered off everything but at this point I’m really lost on what else to do.
