schedule problems(yea I know the most common)

It is the same problem at every table as we are just a bunch of adults and our schedules do not align, I am the DM of a table with my friend group and I work on 14-day shifts, another is doing a master's degree, and another is finishing uni, other works at a hostel, and other have a 5x2 5 to 9, and its impossible to coordinate, we have not played in 4 months now and as a dm I am not satisfied with the story progression, I love my friends I truly do, they are an awesome group but for my brain to be able to spin a good narrative I need a bit more consistency. we first tried to do a 1 time a month and it did not work, now I tried talking to them to try to play in a more async way, have a hub and go on missions with different people of the party but they want to play all together that is the thing they like about ttrpgs (yea I know its an awesome friend group) they are excellent players and awesome people but I want to play more often with my main party, what I want with ttrpgs is to spin a complex collaborative improvised narrative. I am considering looking for another group but I want to see if we can get to an agreement with my current group.
Does anyone have any recommendations for me to play more often with my friends, or do I have to find a new group?

thanks in advance, we are going to see if we can meet soon and talk things through and I want to get there with more suggestions to fix this problem.
