Have you tried downloading the most current public one 0.5.5.2?
Yep. Still won't launch. It generates a log, but all that's in it is something about OpenGL and drivers not supporting something or other, which again I just assume to mean that my drivers need updating which would normally happen automatically if I connect to the internet-- I just can't now. The network card on my laptop is super finicky and maybe half melted(?) It gave up the ghost, like, a year ago. Then my basement flooded, so I moved it to the garage. Months later, I moved it back into the basement to clear out the garage. When I did, I was able to connect to the internet, so I downloaded a bunch of things like steam updates and itch.io games such as this one to tide me over for when the network card died again (it was running super hot). Accordingly, after about three uses, the network card died again and I havent gotten it to work again since. I assume I'd need to jostle my computer a bit and maybe it'd work for a spell, but my computer's still running Windows 10 it's that old and I dont use it for work or anything anyway so I decided to just let it die and just use it for the offline stuff I downloaded.
