Looks like you have an SSD that is failing since there are a couple of Kernel Panics which mention "Could not recover SATA HDD after 5 attempts. Terminating". It is only a matter of time before the SSD will most likely completely fail. Like @BDAqua mentions, I hope you have good backups because you are going to need them.
FYI, I also see you have Avast installed. When you get your new laptop, there is no need to install any anti-virus apps, cleaning/optimizer apps, or third party security software. Those types of apps usually cause more problems than they solve since they interfere with the normal operation of macOS.

I guess you could try uninstalling Avast by following the developer's instructions just on the off chance Avast was somehow interfering with the SSD, but more than likely the SSD has a hardware failure that will only get worse & may suddenly disappear completely.
