A dynamic QR code that suddenly stops working usually means the service behind it turned it off, most often because a free trial or subscription ended. The printed code still points to that company's link, so only they can switch it back on.

Dynamic codes don't hold your link; they hold the generator's short link, which forwards people to yours. When the trial ends, the forwarding stops.
Renew with the same service, or make a new code and reprint. If you can't reprint, a sticker over the old code works.
Pick a dynamic code with no trial and no scan cap, or a static code if the link will never change.
Most often, the free trial or subscription behind a dynamic code ended.
Only if you control the short link it points to.
No, but they can't be changed after printing.
Dynamic codes keep working once you confirm your email, until you pause or delete them, with no trial and no scan cap, and deleted codes can be restored for 30 days.
