Server Version#: 1.21.2.3939
Player Version#: PLEX for Windows 1.27.1
After upgrading the PLEX Player for Windows client to 1.27.1, the applcation hangs at startup (Not responding) and uses all the CPU . Impossible to use the application (grey screen). The server is working normally and the web client also.
I tried rebooting the PC without success, as well as deinstalling/reinstalling the client. Nothing works !
