Tribler 8.0.7 Does Not Launch on Alpine Linux 3.21.2 x86_64

[crftbt]

There doesn't appear to be an Alpine Linux package for Tribler, but flatpak does work on Alpine. When attempting to launch Tribler through flatpak, the following error is output and Tribler fails to launch. Running as root has a similar message. What would be advised in this situation?
