Crash detection on specific points of the printing

Any one can help me?, I keep printing this model and every single time, the printer have a "crash detection" on those points, could this be a problem from the file? The one with the red circle was the first printing, this one had three crashes, the second one only had two but still are in the same places. Any one know why is this happening and how can it be fixed? Thanks guys!

Any details on the print parameters? Nozzle size, layer height, infill pattern, filament type, temperatures, etc. Best would be to zip up the .3mf file and upload it here. Just looking at the image, the surface of the whole model looks pretty bad.

@fuchsr Im pretty new in the world of the 3d printing, but I can say that in previews models, the quality was pretty good. (this are a couple of examples)

but this time i don't know what is the problem, here it is the zip of the file beak

I've been trying everything, adjust the belts, grased the bars, clean the nozzle...
(another thing I noticed is that maybe is due the vibration on the high spots of the printing that probably make the "crash" but I'm not shure. And also checking the files, each one of them have defects that prusa slicer automatically repair. could this be a reason? )

Print one model slower. possible curves print better slower.

Check for blobs during print, print a temp tower to see what is the best temperature for the filament, extrusion multiplier can help against blobs, lower temperature could help.

Well, after a long check, I discovered that the problem was a large clog in the heater block due to a bad joint of a new nozzle I had put in. I cleaned every part of the hotend thoroughly and it finally worked, I also tightened a couple of screws in the bed that were a little loose and made moving the x-axis vibrate a bit.

Thanks a lot for the help!
