If you can go back in time on the SD card then it wasn't reformatted. At this point I'd suggest reformatting in a PC then trying to reformat again in the Wyze Cam, but ultimately flash memory like this has a limited number of writes it can eat before it blows up.
If reformatting doesn't buy you some more time, then you'll need a new card.. you can keep buying the standard stuff, but supposedly cards with a lot of writes do work, it's just a matter of whether you want to buy cheap and replace or buy expensive and replace less:

As others have stated, class is different. This is the one I use: https://www.amazon.com/gp/product/B07B984HJ5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
Yes you should get a bigger SD card if possible, ~64-128 gigs optimally as they're reasonably cheap up to that point, 256 gets really expensive real quick, and most importantly buy the "Endurance" model and only from a reputable manufacturer like SanDisk or Samsung, as they get overwritten a LOT.
The smaller the SD card- the more it is overwritten and the faster it'll die, the same goes for resolution- 1080p cams will overwrite a lot less than 1440/4k one's will, and will kill the SD card slower (all flash storage has a set amount of overwrites before they die/corrupt).
Since this is for your safety, don't cheap out on it, an extra 10$ might be worth it, as you may not even realize the SD card died a few weeks ago after you desperately need the footage after an accident.
And basically all dash cams, even cheap 2$ one's off AliExpress generally overwrite automatically, it's what sets them apart from just being regular camera's.
You want to buy something built to handle a lot of read/write cycles.
I bought the Samsung PRO Endurance 128GB Micro SD card and a USB adapter.

They are all going to fail at some point. I am using SD cards warranted for use in continuous recording devices from Samsung and Sandisk in both my Wyze cams and my dash cam. Here is one. Amazon says they have a newer version and it appears to be both faster and cheaper. I get about 12.5 days 24x7 HD recording on my pan cam with this card.
I got the idea to use this type of SD card from viewing dash cam forums here and elsewhere.
