There are plenty of counterfeit microSD cards out there. Either with a false capacity (a small card pretending to be a big card), or a junk quality card pretending to be a big brand. You might be getting a card that looks like a good card that someone has recommended, but is actually cheap junk rebranded as the recommended card. Amazon has a poor reputation for SD cards, for example, due to their 3rd party marketplace listings and claims of intermingling of stock between their own stock and their 3rd party fulfilment stock. I buy my SanDisk cards direct from WD, or from a trusted British Pi retailer.
Have you tried the SD Association's SD Memory Card Formatter on a problem card?
Edit: You can test SD cards to try to detect fakes with h2testw on Windows, or f3 on Linux. f3 is available through APT on Raspberry PI OS, but you can't test the card that is running your OS (just other cards through a USB card reader).
