mintmenu:
  Installed: 5.2.4
  Candidate: 5.2.4

Recent upgrade to python resulted in mint menu no longer starting. The following python packages were upgrade prior to the fault occurring:
python-evolution (2.32.0-1+b1) to 2.32.0-4+b1
python-gmenu (2.30.3-2+b1) to 3.0.1-3
python-gnomedesktop (2.32.0-1+b1) to 2.32.0-4+b1
python-gnomekeyring (2.32.0-1+b1) to 2.32.0-4+b1
python-vte (1:0.28.1-2) to 1:0.28.2-1
python-wnck (2.32.0-1+b1) to 2.32.0-4+b1

Many other packages were upgraded at the same time, but this appears from the error message to be a python fault.

The error message generated is:

The error occurs every time mintmenu is started.

Should be some other package. I downgraded all the mentioned package on my system, but that didn't solve the problem.
