During departure when Wing A-Ice is selected ON ENG1 and ENG2 bleed faults are triggered. The BLEED page shows 0psi bleed pressure from both engines and both IP and HP valves are closed (XBLEED switch is set to AUTO):

Switching off Wing anti-ice returns the bleed system to a normal state:

Wing anti-ice can only be selected on when the xfeed valve is setting is changed from AUTO to CLOSE:

This appears to be a bug since it is not necessary to close the xbleed valve for wing anti-ice to be available; It remains closed except for engine start, on ground and a few other situations. When both engines, packs and bleed systems are operating normally it's closed with the xbleed selector switch in the AUTO position.

BTW, wing anti ice will cause bleed fault if you used on the ground afaik

Same to me, i had to close XBleed function. I do not know if this is real life also.

I also have the discusion on Discord IniBuilds
