This failure mode has been jumping around:
* From 2023-01-06 to 2023-03-20 this was happening exclusively on w7u, with one
exception, w10pro64-ru-64 on 2023-01-13 (all with "raw_devices_count: 3").
* Then from 2023-03-21 to 2023-05-16 it happened exclusively on various
debian11-win32 locales, but with "raw_devices_count: 1".
* And since 2023-05-30 it has been happening exclusively on w1064v1507 and
w10pro64v2004 (both in 32 and 64-bit) with 12 instances so far, all with
"raw_devices_count: 3".
