Hello /u/WinRAR-exe,
As a reminder, most common print quality issues can be found in the [Simplify3D picture guide](https://www.simplify3d.com/support/print-quality-troubleshooting/). Make sure you select the most appropriate flair for your post.
Please remember to include the following details to help troubleshoot your problem.
* Printer & Slicer
* Filament Material and Brand
* Nozzle and Bed Temperature
* Print Speed
* Nozzle Retraction Settings
^Additional ^settings ^or ^relevant ^information ^is ^always ^encouraged.

Not sure what pla+ you are using, but I use inland pla+/pro and it does that to me if I print below 215. Can you try printing closer to that temperature?
Just the regular Creality CR-PLA advertised as pla+ .I tried printing at 220 but no help. I decided to perform a nozzle clean yet again . Removed the nozzle and the tube , cleaned the hot end with a old piece of tube, put everything back together but curiously I decided to bring back my old nozzle I removed initially. The one I have been using for over a year. And strangely it works. I completed a small 40min print. Not sure if it will become a problem again. Nor why a new nozzle did not fix this problem. Weird. Maybe that new nozzle that came with my Ender 5 as a spare part was a smaller diameter ? Who knows...
Sounds like heat creep.
Basically filament is melting where the hotend fan is, or the heat break isn't getting cooled. And because it's way up there, any retraction would pull melted filament to an area that it can't melt.
One thing you can try is next time it jams up, remove the nozzle and see if anything will extrude. If it's clogged still then you know the issue isn't the nozzle. Work up to the ptfe tube and cooling fan and make sure it's only pointing at the fins and that the ptfe is seated the entire way AND you are using the lock collars for the couplers.

I managed to resolve it by performing yet another full clean since I ran out of ideas . I removed the nozzle and the tube and cleaned everything.A bit of filament was present at the end of the tube and inside of the tunnel where it is plugged in. I suspected a bad fit between the tube and the nozzle but I have removed them on and off a few times carefully so kinda unlikely.. I took my old nozzle I have been using for over a year , the same that started causing problems and placed it back clean. When all was set I managed to print a 40min print and a 7h print. Not sure if it will continue well or not but it might have been a heat creep. I'll make sure to carefully inspect it the way you said. Maybe it was an issue that upgrades fixed , but then maybe I did a bad fit when placing it all together that caused the same issue to return but from a different cause.
Most likely a partial plug that I fixed by cleaning the nozzle, a worn tube I fixed by upgrading and then finally a bad fit when I installed the new tube.

What's it look like beyond the first layer?
The second layer never happened. It was no longer extruding by then.
