K1Max Bridges not working at 0.45mm

I’m having trouble with printing bridges at 0.45mm layer height.
I run a creality k1 max with 0.6mm nozzle and am using prusaslicer.
The bridges work fine with my 0.24mm profile, but not with my 0.45mm profile.
I have tried endlessly to change settings, but cannot get the bridges to actually bridge. They just drop straight down to the bed.

These are the only differences in the settings of the profile:

This is the result at 0.45mm profile:

And this at
0.24mm:

These are the speed settings I use (for both profiles)

I have tried reducing my briding speeds to half, which didn’t worked. I also tried increasing the bridging speeds, but only got close to having something that appears to be a bridge at short distances by approximating the perimeter speeds (100-120mms) which didn’t feel right.

So am I doing something that is impossible? e.g. printing bridges at 0.45mm layer height with a 0.6mm nozzle?
