Video is Black, no prior issues

I have a **hardwired floodlight cam** that is suddenly having issues. It's been working OK for 2 years and suddenly the videos are black. I can click on them and I will get a msg that the video is being processed (even though it's hours old) and eventually I will see an image for a moment but then it's black. Same result from mobile and logging into my account on my laptop. Clicking on Live errors out. We've had sound issues (crackle/garble) since the beginning but the video issue is new. We have 3 other Ring devices with no issues. I noticed today that videos that were black last night are now showing fine in both app and PC, however not all videos are showing at all. I know the camera notified over night but there are no videos to view/click on. We cut the power to the Floodlight, also reset and set up the wifi again with it working well for a couple of hours but then back to the black videos. The **RSSI is 52** and this cam is very close to an access point in the house. I reviewed some of the KB articles and other posts but nothing has shown to be a solution for this sudden issue. Thank you
