Narrative:

Did not intercept the correct runway arrival transition in ZZZ due to a late change in clearance.flying into ZZZ on the cleared route zzzzz RNAV arrival the clearance was changed to the ZZZZZ1 ZZZ1 transition runway xx. During the descent ATC requested us to maintain 310 knots and then comply with speed restrictions at zzzzz. Selected speed intervene and reset crossing restrictions on MCP because we were now in VNAV speed vs VNAV path. Aircraft was still in VNAV speed passing the zzzzz intersection; so we were continuing to reset the altitudes causing a higher workload than usual. Approaching the ZZZZZ2 intersection we changed to the final approach controller and were given a change to intercept the runway xyl transition for the ILS and descend to 7;000 feet. I did not enter the runway and transition in adequate time to prevent flying through the course. When ATC asked if we had intercepted I replied we had not and were given direct ZZZZZ3 for the ILS.many factors lead to this deviation. First; since the covid flight reduction I have only flown 3 trips and am not as proficient as before. Second; I am not that familiar with ZZZ and am not accustomed to last minute changes since I fly into mostly continent X destinations. Third; the confidence of runway assignment due to our gate location on the side of the airport. And lastly; the knowledge that there were so few airplanes flying into ZZZ during the pandemic that the need for a last minute change was not anticipated.

Title: Air carrier flight crew reported multiple changes to the arrival and runway resulted in a track heading deviation. Flight crew stated lack of flying was a contributing factor.
