Hi, I'm new to this forum, so I'm not sure that I've chosen the correct place to post this. I've been having this problem with my MacBook Pro for a while. It started with some Kernel Panics a while ago. At that time I've been reading some forums and it said that it may be a problem with the RAM. I tried using a freeware memory test tool (MemTest86). I had run the test several times and it showed tons of errors. As I was continuing to run the test it showed less and less errors. After that it worked fine for a while until it started to panic again. I've tried the same again, but to no avail. I've brought the laptop to Apple Certified Service, but they say that everything is fine with the laptop. Here's the Kernel Panic report, I hope that someone could help me diagnose the problem.

try reinstalling new copy on yours Mac
 
I've tried that several times. This last Kernel Panic report appeared after a fresh reinstall with macOS Mojave by completely formatting the hard disc.

Does it kernel panic if you remove your USB audio device?

I don't have anything connected to the laptop apart from the charger. Kernel panics happen regardless of it. I usually use it connected to a monitor via HDMI, but they occur in each of the situations.

com.apple.kec.pthread is what crashed and the last two kexts that were loaded were com.apple.driver.AppleUSBAudio and com.apple.driver.usb.cdc. So it appears to be related to USB audio...
 
Thanks for your feedback and your suggestions. I'll see how it behaves. Few days now no KP occurred. Is it possible that the kexts are corrupted or something? So maybe I should try replacing/reinstalling them?

If you suspect corruption, you can try to do a clean install to see if it restores stability.

Another thing to consider would be defective RAM.
 
This last KP appeared after a clean install. I'll monitor it further. Thanks for everything, we can close this thread I think, I'll post another one if it's needed.
