To supplement the report from my expirience this is happen usually during sleep/wake up, system freeze etc. Actually this is really common malfunction during using btrfs on production. When using on server the risk of loosing data is smaller as the server is always on, however when on laptop computer accidentally risk is kind of high. I have expedienced such zero page faulty as far as I remember 3 times always with "bad tree block 1021977804800, bytenr mismatch, want=1021977804800, have=0" zero page. I never advice to anyone to install on the desktop or laptop BTRFS as because it is a play with a fire soon or later You will loose the data for sure as an enthusiast of BTRS i have also say this product is still in infant state and one shall always be aware of that. For now the only information which one can have from the developer for that state this is because the hardware, the HW shall protect against write zero page on the disk, Nevertheless is very hard to investigate on that level what is going on and who's is the owner of the bug.
