Macbook Freezing and Restarting multiple times

How do I test the cleanOS? Its my first factory reset so not sure how to go on about it. I did the first aid verification through the disk utility and it doesnt show any problems now which is a relief. What else do I do?

You just have to use the clean OS to see if the problem occurs. If a problem occurs with a clean install under the conditions I mentioned, then you know you have a hardware issue. How long do you test it? Ideally, at least as long if not longer than it took for the failure to show before the clean install.

Most SSD failures occur when powering on the computer or waking the computer from sleep. So sleeping the laptop for 5-10 minutes & waking up the laptop could trigger it....I like to let the laptop sleep longer sometimes. Use the Sleep option on the Apple menu to sleep the laptop since closing the Clamshell lid is not always enough. In fact, press the Caps Lock key prior to sleeping the computer so you can watch the Caps Lock LED go dark indicating the laptop did go to sleep (or as sure as you can be). Powering the laptop completely off at night can be useful since the SSD will be at rest & unpowered for a long time which may trigger a failure when you go to power on & boot the laptop the next day.

You can try running DriveDx (free trial period) to check the health of the SSD, but most SSD failures occur with the SSD's controller which does not show up in the SSD's health report. Plus the Apple SSDs have very little information in their health reports. Post the complete text report here using the "Additional Text" icon which looks like a piece of paper on the forum editing toolbar. It is Ok to install DriveDx on your clean install since I know it does not cause any problems that would interfere with your testing.

It appears you have a MBAir 13" 2015 or 2017 laptop (MBAir 7,2).

The Kernel Panic log had this bit in it which seems to indicate an issue with the internal SSD:

Root disk errors: "Could not recover SATA HDD after 5 attempts. Terminating."

More than likely the SSD is failing all things being equal (assuming the Logic Board does not have any accidental liquid damage). I hope you have a good backup since the SSD could fail completely at any time. There is a slim chance you could have some sort of software issue which is causing the problem, but we would need to examine the EtreCheck to see if anything stands out....it would also include summaries of other Kernel Panic Logs so we could see if there may be any pattern as well.

People should always have frequent and regular backups of their computer and all external media (including the cloud) which contains important & unique data. There are a lot more new ways to permanently lose access to the data stored on the internal SSD of the more recent Macs due to all the hardware, software, and security changes.

If you decide to go that route, then make sure to erase the whole physical SSD before reinstalling macOS. Make sure to thoroughly test the clean OS before you try to restore/migrate from a backup, before you install any app, and before you sign into your AppleID or iCloud. If booting into a macOS 10.13+ installer, then within Disk Utility you will need to click "View" and select "Show All Devices" before the physical SSD appears on the left pane of Disk Utility.
