I have same issue, mine ran out 28th April 2020, yet It let me upgrade to 5.2.7.9 (08th May 2020), but no further, 5.2.7.10-12 give the same problem for me.
I've now just left it on 5.2.7.9 which seems to work for me now. I'll wait until 5.2.7.x becomes mainsteam - presumably lots of people will...
