Recent chromium/chrome/edge updates limits the number of media player opened simultaneously.
Hence my test which consists of 88 successive videos in a loop does not work any more and the browser tells that it cannot open so many MediaPlayers.
Are you aware of this issue and if so is it solved in recent versions of PsychoPy ?
Following is a trace opening my test on Chrome 91.0.4472.1 with Psychopy 2021.1.4 (got the same with recent edge browser)
