Having had a close relationship with ADOBE for decades they supply the glue
which holds my entire life together  I can tell you they will have a
downloadable fix any day if not minute now.
On my computer such things are happening almost automatically. They restart
my computer twice a week with things going on. Apple. Microsoft. Adobe. Not
in that order.
With Adobe its good to leave it to dry out in the sun for a few days first.
