On February 9, the Pennsylvania Supreme Court issued an order in Carter v Chapman, 7 MM 2022. The one-sentence order says that the 2022 election calendar is suspended until the Court decides the case on the boundaries of U.S. House and legislative districts. This means it is somewhat likely that the primary will be postponed. It had been set for May.
It would be much easier if the state permitted candidates to get on primary ballots by paying a filing fee, but the concept of eliminating mandatory petitions to get on a primary ballot is alien to Pennsylvania. No one in Pennsylvania state government ever seems to suggest the idea, even though that is policy in a majority of states.
