Cant open AppImages without being root?

[ghost]

Distribution (run cat /etc/os-release):
PopOS 18.04

Related Application and/or Package Version (run apt policy $PACKAGE NAME):
Lisk Hub and all AppImage packages.

Issue/Bug Description:
Also, this isn't related, but, I also can't run AppImages with opening terminal and running sudo nautilus then running the appimage. Not sure if I should open up another issue for this. When I try to run app images from the cli I get this output.

nolan@pop-os:~$ cd Apps/lisk-hub
nolan@pop-os:~/Apps/lisk-hub$ ./lisk-hub-0.9.0-x86_64.AppImage
Cannot open /home/nolan/.cache/thumbnails/normal/fdd59768a8cbf2186cab3d586fba89f2.png for writing
installed: X-AppImage-BuildId=34b45a20-7484-11a8-2c2b-e9699a5440fe image: X-AppImage-BuildId=34b45a20-7484-11a8-2c2b-e9699a5440fe

After changing permissions to that directory, now i just get this:

nolan@pop-os:~/Apps/lisk-hub$ ./lisk-hub-0.9.0-x86_64.AppImage
installed: X-AppImage-BuildId=34b45a20-7484-11a8-2c2b-e9699a5440fe image: X-AppImage-BuildId=34b45a20-7484-11a8-2c2b-e9699a5440fe

Looks like a permission error on /home/nolan/.cache, perhaps?

Closing, since AppImages do seem to work on Pop!_OS 20.04 (at least).
