Possible Print Nozzle Collision?? Time-Lapse Video
It looks like the printer nozzle seems to knock into the printed part. Stop the video at 29 and 30 seconds and look on the left-hand side of the print.
At first I thought it was insufficient support structure, brim and lack of raft, but after beefing that up, the issue still occurs and on different models.
I've done a re-position of the PINDA sensor and re-calibrated everything along with the first layer calibration.
I am using the latest Driver/Software download and the GCODE is output using the Slicr Prusa edition 1.38.6.
Lift-Z has been upped from 0.5mm to 0.8mm to rule that out.
Print material is Prusa supplied PLA.
Any ideas?

Hard to tell, but probably PLA curl. That left side looks thin and the PLA can cool unevenly and curl up, catching something on the extruder, like nozzle, heat block, even pinda. This is not uncommon in 3D printing. If this is correct, try to identify what caught. You can adjust slicing, like more perimeters, more or less infill. You can adjust temps and fan speed to keep limit the curl.

Looking at the video, something seems to have gone wrong around 26/27 seconds with the support. There's a gap there.
Something I was a little confused about when assembling the print head assembly was the correct way to tension the spring loaded filament hatch *for want of a better word). There are two screws that are spring loaded which holds the idler and the feed wheel together.
