Temperature drop during print

Hi!
Using Luban 4.6.2 or Cura 5.3.0 or PrusaSlicer … I set the temperature to 220 (PLA) and it starts printing fine. After a while the temperature drops to 200 and I get the “clog” warning and the “clicks” … the extruder is not able to push the filament anymore …
What can I do???

I have the same problem and can’t find a solution…

Edit: check if the extruder you choose has different initial layer printing temperature, that was the problem for me.
