Ring Spotlight Cam Battery not accepting recharged batteries

The battery in my Ring Spotlight Cam died a couple of weeks ago, and when I went to replace it with a fully charged battery today, it doesn’t acknowledge that the battery is good. The app still shows the battery as being 3%, despite having been fully charged, and the battery light inside the compartment is red. I then tried to use the old battery after charging it, but same result, it just won’t acknowledge that there is a charged battery, regardless of which side I insert it in (or even if I put both batteries in at the same time). I have already tried to reset the camera by pressing the setup button for 30 seconds, but the camera does not react at all. For some background on the camera’s condition, it is kept under cover on the porch so has not been exposed to water, and it has been above 80 degrees for months, so it’s not an issue of the camera being too cold. The camera itself is less than a year old and has never given me issues before, although this is the first time the battery has actually fully died before I was able to replace it. Any ideas on what I can do to fix it?
