I'm not really sure what's going on, but there have been improvements
to the write time tree checker since kernel 5.3. It could still be
true that a memory related bit flip escaped detection and caused this
problem. But it could also be an early indication of drive failure.
I suggest updating to a more recent btrfs-progs and running 'btrfs
check --readonly' and post the output to help confirm the problem.

I'm not sure what it's telling us or if it can be repaired. Until you
hear back from a developer I wouldn't try to repair it. Also, I can't
tell if you upgraded btrfs-progs so you need to make sure to do that
before attempting repair.
For now, if you're using a 5.11+ kernel, try to mount with -o
ro,rescue=usebackuproot, and see if you can freshen backups. If that
won't mount ro, then try -o ro,rescue=all, but be aware that bad csums
will be ignored, so it's possible any corrupt files will be copied
(normally they aren't). This is easier than btrfs restore, but if the
file system still won't mount then that's the next step, before
repair. You definitely want newer btrfs-progs if you have to use
restore.

It's also best to get advice on #btrfs on IRC libera.chat, because
back and forth by email is cumbersome. But hopefully Qu will have
better news.
