Hello Tom,
If there is any way I can help further... I am definitely not able to do a dev environment and local build, but if we have a windows developer reproducing the issue between 11 and 12, then that should help. If someone makes a debug build available to me, I can provide additional help based on that.
Please, download from this link (Google Drive):
Postgres Debug (64 bits) HEAD.
