Well, I'm afraid that there is nothing more we can do now. I discussed your situation with my colleague, and now the only thing we can think of is an Avast false positive.
How is the computer running now? You mentioned that without Avast it works better. Is it the paid version of the product? If it's the free one, I would recommend you to uninstall and stay with Microsoft Defender, the built-in Windows antivirus. If it's the paid version, then it's up to you if you would like to uninstall it.
In case you uninstall it, make sure that Defender is enabled, since your latest logs indicate that it is disabled too:
Settings > Privacy and Security > Windows Security > Open Windows Security
At the Security at a glance window, check if anything is needed so Defender will get enabled.
Let me know about your thoughts.
