It looks like this problem was caused by a change a couple of months ago for Issue39885:

https://bugs.python.org/issue39885

which had the side effect of disabling the cut and copy context menu items.

A fix for that regression was just merged yesterday so the problem should be resolved in the next set of releases,
3.8.4 and 3.7.8, which should both be available by mid-July.
