645M freezes after saving Workout (FW 5.90)

My 645M freezes after every workout just after saving it. Spotify continues to play, but the watch is completely locked. The workout however is saved correctly and can be synced after killing the watch and turning it back on.

Be careful with 5.90!!!

  • I have had this issue ongoing with my 645M going on for months now. I am currently on 5.7 firmware. 
    -Typically I'll have a freeze when saving the run i've just completed. I know now to give the watch around 30 seconds without pressing any buttons and it will find some memory, and finish the saving process. 

    -I have had occasional hangs while pressing the lap button in workouts, which is very annoying as I use this feature a lot to take splits of my workouts. 
    this is when I am just running, without using a pre-programmed workout.

    -I also have had hangs when using pre-programmed workouts, for example my workout might have a section that is 15seconds on, and 15 seconds off, i have had the countdown start, but then skip a couple of beeps, and then not start the lap at the right place.
