  • Reproduction steps:

    Just ran installer over previous 21.14 beta build.

    Actual result:

    The installation never ended, I got dumps, for a while 2 icons in Windows taskbar (probably GUI crash), “Loading protection” remained showing, and after some minutes disappeared, only 1 K. icon remained in Windows taskbar, saying "Starting..."

    I reboot, and the GUI did not start, so executed manually and got the same behavior, but this time after a while the K. icon also disappeared from Windows taskbar.
