FWIW, this looks the same issue I am getting (reported last month:
https://www.postgresql.org/message-id/f444a84e-2d29-55f9-51a6-a5dcea3bc253%40burgess.co.nz)
I get the same Process Monitor output, including BUFFER OVERFLOW
entries. No sign of any process other than postgres.exe touching the
WAL files.

Hi!
I think what it would be most helpful to run "process monitor", so that you get
a log of the system calls and errors; perhaps that shows some details that
we cannot get from the error message.
Process monitor shows huge number of DELETE PENDING results from
