I running the latest TestComplete/TestExecute along with latest Edge browser version and I am experiencing the same issue where Click() is not working as it should for buttons that have always worked with no issues.
Something is still not stable with TestComplete vs. the chromium updates that keep coming out with Chrome or MS Edge. It likes it gets fixed to a degree and then chromium changes again and TC\TE are in a broken state again. A see-saw effect.
I won't mind seeing some patch updates from SmartBear for these issues instead of waiting for the next minor update for TC\TE for keeping up with the chromium and constant browser updates.
