which log exactly do you mean, the Windows event log, parts of it, or the logs by Wireguard itself?
The problem is that the hang happens on bootup, before user login (but indeed I was not clever enough to check the WireGuard logs from before the failure).

I tried to boot one of the machines with boot/startup logging (I'm not sure this is the correct English translation, it is one of the options next to safe mode in the WinRE),
and ntbootlog.txt ended during network driver loading.

I don't have the file at hand, but could access this and the WireGuard log hopefully later this week when the affected user is back from travelling.
