Issues in Changing Material in Ultimaker 2+

[curiousmech 0]

Hi,
I have an Ultimaker 2+ and its giving very strange issues.
I am unable to Change material in it, it just halts on the screen after the bar is completed. You can see the attached pictures.
I have tried changing heater as well as thermistor but its not working and giving me same issue

I have also updated the firmware but it doesnt work

Kindly guide what can be issue? Is it issue with PCB or some chip ?

I would check the material settings as a first step.

"minus 1C" is not a valid target temperature - that's for sure.
