Systemctl snap mount issue - Ubuntu 20.04

For the last few weeks, I have been unable to perform any updates on "Ubuntu Software", nor have I been able to update new software via snap. I can assume it is all related to the same systemctl snap mount error message, shown below:

$ sudo snap refresh
[sudo] password for ryanalexander: 
error: cannot perform the following tasks:
- Mount snap "snapd" (18357) (systemctl command [start snap-snapd-18357.mount] failed with exit status 1: ERROR:systemctl:start not implemented for unit type: snap-snapd-18357.mount
)

Another example, when I was downloading vscode. Notice the similarity:

$ sudo snap install code --classic
error: cannot perform the following tasks:
- Mount snap "core" (14784) (systemctl command [start snap-core-14784.mount] failed with exit status 1: ERROR:systemctl:start not implemented for unit type: snap-core-14784.mount
)

I haven't been able to find anyone with a similar issue, the only thing I could find with the same error message was this, which was resolved by updating snapd. This is the message I see when attempting to update snapd via the Ubuntu Software GUI:

Unable to update snapd:
Cannot perform the following tasks:

and that's it. I have an image of the error popup that I can add on here as well. Interestingly, sudo apt update && sudo apt upgrade run normally.

For reference, here are my system specs using neofetch:
