Following the completion of his entry-level with the Kings, Rymsha was not tendered a qualifying offer by the organization, releasing him as a free agent. On September 8, 2021, Rymsha signed a one-year contract with his former ECHL club, the Fort Wayne Komets. In the 2021–22 season, Rymsha was the offensive catalyst to start the year with the Komets, before he was signed to a professional try-out with the Hershey Bears on November 11, 2021. He later established a role on the team with the Bears and secured an AHL contract for the remainder of the year on January 23, 2022. He would make 49 regular season appearances with the Bears contributing with 1 goal and 9 points.
