I hope I'm allowed to bump this post as I have a similar issue on a non-domain computer, but with some windows features removed (ie. Internet Explorer) to be more secure (let's call it minimal image)
Complete fresh installation (including Reg and Temp data removal) Right after the start of the Host (or the service) it crashes with "Fatal error. rfusclient.exe is corrupted."
Even with procmon I cannot find the cause of it, the crash happens right after reading some crypthography registry settings - on other regular Windows 10 installation the Host is working as expected. - Is there a requirement to have Internet Explorer available?
