The first five months of the year proved unsuccessful for Majchrzak, winning just three of his first ten matches across the ATP Tour and ATP Challenger Tour. He began to turn it around at the 2021 Italian Open where he qualified by defeating two top 100 players in Alexei Popyrin and Yoshihito Nishioka.

At the 2022 ATP Cup, Majchrzak won all his three matches and helped Poland reach the semifinals for the first time, before testing positive for COVID-19 and having to withdraw late from the tournament. As a result, he was unable to participate at the 2022 Australian Open qualifications where he was seeded fourth and thus possibly missing the first Grand Slam of the year. He nevertheless entered the main draw after replacing Jenson Brooksby who withdrew due to COVID-19. He reached the second round for the first time at this Major with a win over Andreas Seppi. Majchrzak lost to Alex de Minaur in the second round.
At the 2022 Tata Open Maharashtra he reached the semifinals of an ATP tournament for the first time in his career defeating second seed Lorenzo Musetti. As a result, he reached the top 75 in the rankings on 28 February 2022.
In May at the 2022 Geneva Open he clinched the biggest win of his career defeating 8th seed and World No. 41 Alexander Bublik in the first round in straight sets. He reached the quarterfinals only for the third time in his career defeating qualifier Marco Cecchinato.
Majchrzak competed for Poland in their Davis Cup tie against Indonesia. He won two rubbers, losing just one game between them, to help Poland claim victory, 5-0.
In September at the 2022 Sofia Open he reached his third tour-level quarterfinal of the season, for a second year in a row, defeating Ričardas Berankis and eight seed Oscar Otte. He lost to eventual champion Marc-Andrea Huesler. At the 2022 Busan Open in South Korea, he won his fourth Challenger title defeating Radu Albot. As a result, he moved 20 positions up back into the top 100 at No. 82 on 24 October 2022.
On 9 December 2022, the International Tennis Integrity Agency announced that Majchrzak had been provisionally suspended after testing positive for banned substances at the Sofia Open, the Japan Open and the Seoul Challenger. In June 2023, the agency suspended Majchrzak for 13 months, while acknowledging that Majchrzak had not "knowingly or intentionally" committed an offense.

### 2024: Comeback, first Challenger titles since 2022

Majchrzak's suspension ended on 29 December 2023. He returned to professional tennis on 31 December 2023.

He lost in the semifinal to Marco Trungelliti in a rematch of the previous week's final. Following this he won another ITF-level title at Sharm-el-Sheikh without dropping a set.
In May, he returned for form following some injury problems in April. He reached the final the Macedonia Open but lost to teenager Joel Schwärzler in the final.

During this tournament, he defeated former top 10 player Pablo Carreño Busta on route to the semifinals where he lost to compatriot Maks Kaśnikowski after suffering from a mid-match wrist injury.
