The first two layers are vital for any 3D printer. This is often why you would print with a raft.
The extruder has an immense pressure built up in there, and if the nozzle is too close to the platform (essentially it’s closed off) for too long, something will fail. This usually ends with the teeth digging a groove into the side of the filament, or “stripping out.”
PLA is another beast, and adds to the problem. Because if PLA’s low liquefying temperature, and large difference between the temperature where it starts to liquefy and where it’s actually soft enough to extrude, it will react to back-pressure more that ABS. Often, the heat will propagate back up the filament, making the inside of the extruder like a honey bear, and the pressure required to extrude at that pointy is impossible.
The best solution to this is the actually back the plastic out while it is molten, snip the gooey end off, and run fresh plastic through. Run a noodle for a few seconds, and you’ll be back up and running.
Never let the extruder stay heated too long when it’s “empty,” or it will solidify and truly clog.
Tram the platform carefully. Run a large print or a test print that covers most of the platform, watching the first layer carefully. You’ll see where it’s too close pretty easily, and you should be able to gently adjust the tram as it prints (carefully.)
