It should also ignore ERROR_BAD_NETPATH (53).

Updated with ERROR_BAD_NETPATH (53).
What about following errors:
eryksun commentedon Aug 4, 2021
ERROR_NETWORK_ACCESS_DENIED (65) should probably be added to the ignore list. I don't know whether it occurs in practice, but we have it mapped to EACCES in PC/errmap.h. The common access error is ERROR_ACCESS_DENIED (5), even on a UNC share with restricted access.
Add ERROR_DEV_NOT_EXIST (55) only if you have a case that fails with this error code. It's from the NT status code STATUS_DEVICE_DOES_NOT_EXIST. This might occur when trying to automount a device that's pending removal (see the implementation in ReactOS IopMountVolume [1]), but I can't create this condition. I think a device object would need to be practically stuck in the pending removal state for this to be a practical problem.
ERROR_LOCK_VIOLATION (33) isn't relevant. It's an I/O access error for a locked range of a file. realpath() doesn't read or write file data.
For the others, I'd wait for an issue to be reported.
