I had Aircraft X going into ZZZ and there was a VFR aircraft that turned and climbed into Aircraft X. I cancelled the approach clearance and climbed Aircraft X to 4;500 ft. Aircraft X advised climbing for an RA. I looked around to advise the person in charge of the area and could not see anyone. As I continued to work with aircraft not checking in or responding to correct call signs; I turned and asked for help and again did not see anyone in the area. I regained control but several aircraft were high on the approaches. I think everyone was separated by the standard separation but I honestly don't know. I had Aircraft Y going to ZZZ1 who said they wanted the GPS 12 Approach; so I cleared them direct ZZZZZ an IAF or IF for the approach and they turned south into a 5600 MVA (Minimum Vectoring Altitude). I issued a Low Altitude Alert and Climb to 5;600 ft. They didn't comply; I issued a heading north and a climb. They were not responding which increased my workload even more. Based on their position; I might [have] even had an airspace violation. Again; no one seemed available to help. The airspace could be changed to help prevent VFR aircraft from being able to climb to the approach altitudes of ZZZ or [nearby] airports. Mainly I needed assistance and was not able to obtain any.
A TRACON Controller without an Assist reported an unidentified VFR aircraft climbed into traffic on a final approach course and another aircraft deviated from their course into a higher Minimum Vectoring Altitude Area.
