There may be some small fragments or other things entering the nozzle, preventing normal extrusion. The simple way to test this possibility is to manually increase the temperature on the machine and manually extrude some plastic from the nozzle. Observe and ensure that the plastic extrusion is continuous and stable. If you find a problem, you may need to clean the nozzle. Please contact your printer provider to obtain the correct method for cleaning the inside of the nozzle.

If the extruder is not blocked, it will be useful to check some settings in the cura slice. For example, if you are trying to print a very small layer height, such as 0.05mm, there will be only a small space for the plastic extrusion nozzle. There is only a 0.05mm gap under the nozzle, which means that the plastic may be difficult to extrude. Double-check that you are using a layer height that is appropriate for your printing. In basic-quality-layer height, if you print with a very small layer height, try increasing the layer height to see if the problem is solved.

If you have checked all the above conditions, but still have the problem of unstable extrusion, then you may need to check your extruder for mechanical failure. For example, many extruders use drive gears with sharp teeth that bite into the wire. This makes it easier to pull the wire before and after the extruder. This extruder can usually adjust the pressure of the gear on the wire. If the setting is too loose, the drive gear will not bite into the wire deep enough, which will affect the extruder's ability to accurately control the position of the wire.

Thanks to solved the problem.
It was about the slicer.
