How to reproduce

Open Slicer
Import object to print
go to Quality TAB
Change Ironing type to "ALL TOP SURFACES OR TOPMOST SURFACE"
Ironing flow: 35%
go to Speed TAB
Change Ironing Speed to 20mm
Slice the Plate and then Print Plate
The bed and nozzle will begin to heat up and in Devices it gets stuck at 0% with "Heatbed preheating"
I left it at this stage for more than 10minutes and nothing has moved.
Using External Spool or AMS same results

Actual results

Nothing happens, gets stuck at this screenshot below and doesn't move.

Expected results

should start homing and raising the bed to get ready to print.
