I also confirm the defect described in this post:

RE: Defect during printing PS 2.3

I'm not sure exactly what those pictures are trying to show or what your defect actually is.  Your explanation of your issue is unclear.  The pictures show a few decent layers and then what appears to be subsequent layers not adhering to the layers below.  That could have a myriad of causes, most of which are unrelated to software. 

Also without knowing what your issue is  I can't see how it relates to a bulging wall issue or confirms it.  The bulging wall issue hardly needs confirming either, its been confirmed for literally years. 
The issue is still there and hasn't changed in I don't know how many releases.  It's what's referred to as an 'evergreen'.  Its just that every few months someone new notices it and starts yet another thread pointing it out.  Not realising that there are already MANY threads about it and just about every option has been tried already.

If you have an repeatable issue with Prusa Slicer then the correct course of action is to document it clearly showing what the expected versus the actual outcome is.  Take all that documentation as well as the project that allows the issue to be duplicated and then go to the PS github located here https://github.com/prusa3d/PrusaSlicer/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc

After doing a search for any existing issues to make sure you aren't creating a duplicate you can then open an issue.  Please include all the aforementioned relevant information in the issue as well as all the details the issue template asks for like versions numbers, operating system etc.

Issues created on github get a proper issue number and are tracked.  They will also be seen by the developers.  This is a user to user forum and while we try to help as much as possible if you believe you have a genuine problem that needs a software fix then here is not the place to report it.

As a last resort if you don't think the software is suitable for what you are trying to achieve then try other software.  Repeat until you find some that works how you want it to or you run out of software to try.

Your problem appears to be very different than the issue being described in the various "bulge" threads. The strands of filament being pulled across the center of your circular print are not adhering to the underlying layers and get pulled across the opening as the nozzle moves. Poor inter-layer adhesion can be caused by many things, but a few things to try:

• Reduce speed. If the nozzle is moving too quickly, the filament will not adhere properly to the layers below.
• Reduce cooling/increase nozzle temperature. If the filament is insufficiently melted, it will not adhere properly to the layers below.
• Reduce layer heights. If the layer height is more than approx. 80% of the nozzle size, or is close to the size of the extrusion width, extrusions will have a circular cross-section instead of the "squished oval" required to give sufficient flat surface area to contact adjacent layers, resulting in port inter-layer adhesion.

Good day! I'm sorry, the problem was in the hot end. Thanks everyone! Although the circumstances did add up in an interesting way. This is essentially an accident. When I updated the program in the same time there was a breakdown hotenda.
