This print is driving me nuts

I'm trying to print a piece which is an "arc". This is the side view:

Side view

I had a somehow successful print with an orange PETG but never again after many prints. I tried the silver PLA and always ends up on a part looking like over-extruded. I tried many combinations. This is when it gets messed up:

Problem

I even get "crash detections" mid-print. This is the slice around that time from Prusa Slicer:

I'm not sure what I'm doing wrong nor what else to debug. Thanks!

Printer: Prusa i3 MK3S+

Layer Height: 0.3mm

Nozzle: 0.4 mm brass

Filament Setting: "Prusa PLA" from the template

Save project from the File menu (Save as) as an 3mf file. Zip it (IMPORTANT!), then upload here. That gives up STL *and* all your settings.

Eeeep

All I can say is - that was not designed for FDM printing - but with enough supports .... EEEEP

Nozzle diameter / layer height ratio

Bridging and/or overhangs are usually best printed with a layer height not exceeding 50% of the nozzle diameter.

Get an injection molder

Seriously - that is not a good FDM design.

separate

Print in the orientation swiss posted and make the feature that sticks out separate. Screw, clip on, glue whatever, it'll probably be much stronger and it will certainly look better
