ParrotOS install giving bad unsquash config error

I installed Parrot (5.0.1 Home edition, amd64) onto a USB stick using Rufus to use as a live boot on an old laptop I had lying around. I then decided to install Parrot onto the laptop harddrivehard drive itself with the onboard installer. I left all the install settings as default and selected the "Erase data" option, created a username/password, and started the install process. It started as normal, wiped the drive, and created its' partitions. Then it threw up an error message:

Installation Failed
Bad Unsquash Configuration

The source filesystem "/run/live/medium/live/filesystem.squashfs" does not exist

Now, I am by no means a developer. I had intended this to be my learning tool into Linux type systems instead of Windows, which I'm used to. I've never heard of this error, and looking around on the internet and stack exchange I couldn't find a solution to a problem like this one that I thought I had a chance of fixing myself. *Sidebar: It didn't throw up the error until after the drive was wiped. Windows is gone, and the laptop now won't boot without the usb stick in it, because there's no host OS anymore.* I've tried rerunning the installer with custom partitions following a few guides online but that didn't change anything. Can I salvage this? I assume it has to be a bad live install of Parrot, but I don't want to try anything else on my own.
