It could be that only the installer has issues. If you're dual booting have you tried launching the already installed program from your windows partition?
Otherwise I would try launching the installer from the wine command line to see if it gives you a specific error there.
Don't think I necessarily believe things or don't believe them based on one assertion by someone. I am able to hold it in my mind with a certain confidence level attached. Of course that doesn't really answer your question, only kicks it to "how do you form that confidence level?"
Have you considered casting zone of truth?
You can set up a command to transcode into AV1 once a download completes. Would that help?
