Thank you but I am not a fan of installing so-called "utilities" and also pasting my system details. I have seen enough fraud so... Not to offend.
That is your prerogative, though etrecheck which we have been recommending for a decade does spare us asking 20 questions about your macOS and third-party software installations that may be contributing to the problem. Etrecheck completely protects your privacy and would not reveal anything that would lead to fraudulent activity.
When you encounter Disk Utility First Aid errors in recovery mode and subsequent runs of First Aid do not give you a green success result, then your drive is likely damaged and needs to be replaced followed by a clean nstall of macOS and Time Machine migration.
