is that 150% flow ?
that's way too high. Should be mearer 100 - ie somewhere between: 90-110.

best advice is for you to download prusaslicer and try that.

Cura is just way more hassle than it'e worth.
I no longer bother with installin cura on my work computers.
It would be purely for diagnosing other people's problems - and it's just so much quicker to say: use something else :-)
