Hi,
I have tested in my lab and find I can install the client software and enroll into Intune successfully.
Then I go to check the log, I find I also has "FATAL: StartTargetServiceWithOtherServices: IServiceHelper::StartService() call to start SignalingAgent failed with hr=0x80070424. Ignoring the failure since this is not the target service". But I find the following logs "Enrollment Utility: completed execution." which mentioned the enroll has completed. So I think this error can ignore.

Please check in the portal to see if the device is enrolled successfully and see if we have the above logs indicate the completion of the enrollment.
Hope it can help.
