Narrative:

I was working all positions combined during the covid reduced staffing period. Both ZZZ and ZZZ1 were in their north configuration. I had turned aircraft X to a XXX heading for a vector to the visual approach. I had released aircraft Y on an initial westbound departure heading. During the sequence of events; I had forgotten that aircraft X was a ZZZ1 arrival; mistaking him as a ZZZ arrival. Both arrivals are vectored in a similar manner to the visual approach in this configuration from the north and the aircraft X call sign made me think ZZZ arrival. The aircraft Y departure had to build a little altitude before I could turn him north because the temperature was decreasing the climb rate today. I mistakenly cleared aircraft X for a visual approach to runway xx and then he corrected me with the 'runway xy' readback. I had planned to go right to aircraft Y for his turn to the north; but I realized if I didn't correct aircraft X first; he might turn early towards ZZZ1; so I corrected his heading and altitude first. The lost time; however; resulted in a loss of lateral separation after I turned aircraft Y to the north.this resulted as a loss of awareness about my aircraft and what they were doing. If I hadn't made the mistake of clearing aircraft X to the wrong airport in the first place; the sequence would have worked out with enough time to turn aircraft Y in a timely manner.
