I don't know how this happens to me but i always have trouble with Bottles. And not just the slightly bad UI, but like today, i have an installer that i can run directly with Steam that i cannot get to run in Bottles. When i last used it a couple years ago i did get what i needed working successfully but i remember it being a struggle.
(edit: removed because I was confusing Bottles and Boxes, no need to leak wrong ideas)
Bottles is a wine/proton runner, not a VM manager. I think you might be mixing it up with Boxes?
Yes! I am indeed, thank you! Bottles has been useful, though I haven't used it in years.
