[Bug report, UE5.2.1, UnrealHeaderTool] UHT errors on VS output log.

VS output log (integration logging) is filling up with errors at random times from UnrealHeaderTool lately (UE5.2.1, never did this before). What is this a symptom of? I did not have this issue before on UE5.2.1 and wonder what could be interfering / where to look. There is no build error or anything, just an annoyance.

Seeing nothing on the AV side. Think it might have been an auto update of something on the EPIC launcher, as nothing else changed, not even the VS version.
