MDEV-28178 Windows : sporadic ER_ERROR_ON_RENAME .. (errno: 13 "Permission denied")
On affected machine, the error happens sporadically in innodb.instant_alter_limit. Procmon shows SetRenameInformationFile failing with ERROR_ACCESS_DENIED. In this case, the destination file was previously opened rsp oplocked by Windows defender antivirus. The fix is to retry MoveFileEx on ERROR_ACCESS_DENIED.
