Calibration hangs after 16th blue patch

Hi, I'm trying to calibrate my u2725qe using the latest version of dell colour management but for some reason the app always stops after the 16th blue patch is shown. The mouse is still visible and moves, caps lock is working but the screen is stuck and I can't get the desktop back or even get the machine to shutdown normally via the power button, I have to force a power off.

Running win11 all drivers, etc are up to date.

Anyone experienced this before and have a solution?
