Angle slanted roof

[Nightlow]

Can someone kindly answer whether it's possible to achieve this angle with Hålkälslist or is it a lost cause? It's the angle where the flat ceiling meets the slanted ceiling that I can't seem to get right with the moldings.. I've searched the forum but can't find a good answer, tips are wanted from an extremely frustrated person.

A ceiling block is your savior!

don't know if it helps but I usually think that the fence on the saw is the ceiling and the actual saw table is the wall, if you lay the trim like that and start with 22 degrees (so ignore tilting the blade itself)
In this case, the groove will then look diagonally up towards the ceiling

Can any kind soul answer if it's possible to achieve this angle with Crown molding or is it hopeless? It's the angle where the flat ceiling meets the sloped ceiling that I can't manage to get right with the molding...

The problem might already be solved but this is how it looks in our place, one room without molding covering the gap, another with a wedge inserted to create a nice finish:
