Can't run Cinny on Linux Mint: "GStreamer element appsink not found. Please install it" / "error while loading shared libraries: libssl.so.1.1"

[jedomed]

Describe the bug

Using the AppImage I get the error: "GStreamer element appsink not found. Please install it"
Using the .deb file I get the error: "cinny: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory"

In both cases the app opens, but it's a blank white window. When I run it from a terminal I get the two different errors.

Reproduction

chmod +x Cinny_desktop-x86_64.AppImage
./Cinny.AppImage

or

Install .deb file, cinny

Expected behavior

No response

Installing libssl1.1 from http://nz2.archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2.22_amd64.deb makes the .deb work (but not the AppImage), though that's kind of not an ideal solution...
