ERJ-145 flight crew reported EICAS flap fail message during descent to land.

Narrative

Landing runway XX at ZZZ; the PF requested flaps 45 and landing checklist. We received an EICAS 'Flap Fail' message and opted to perform a go around so we could run the QRH checklist. We requested priority handling; received vectors and climbed to 4000ft per tower request. Our EICAS displayed flaps 45 and our RMU (Remote Monitoring Unit) displayed nothing on the left side of the aircraft and 41 on the right side of the aircraft.I ran the QRH procedure and once we were finished with the checklist; we returned back to ZZZ for the ILS XX with a safe landing. The PIC requested ARFF (Airport Rescue and Firefighting) vehicles to be ready to inspect the landing gear and aircraft abnormalities once we were clear of the runway.Suggestion: The PIC and I had a conversation regarding the speed on the go around as we encountered icing on the climb. The QRH wasn't clear on a situation where icing might be present. There was also no guidance on the QRH regarding recycling the flaps or keeping them in set position.
