In 2022, usage of AirTags exploded, with "Track your luggage/people/etc" stories all over. Those use BT Low Energy at 2.4GHz as well, though I think they also have UWB at a higher frequency and wider range. Another thing which has grown a lot is wireless earbuds...there was also the popularization of 802.11ax WiFi 6...many more devices have that now--which is the same 2.4, 5.0 (and additional bands) as before, but a different modulation.
I didn't think about COVID detection apps, that's a good guess as well.
It could be something else altogether different but systemic--like maybe they use a radio module where the lead solder process was wonky and they're all going bad right now. Or capacitors. I mean, leading up to a 2006 directive for RoHS, there was a huge rash of lead free solder problems with consumer electronics. Everything from XBoxes dying to my JetDirect print server card in my printer going bad...
If I was doing a drive to test this, I'd go far into a local park or similar as far as you can and try it there. Don't bring your phone or anything else electronic.
