All that's really up for debate is at what point that doom comes about. Any attempt at a crowdfunding campaign can surely be described as "very unlikely to succeed". What's more, Alex likely realizes this so the crowdfunding campaign may become the new Osana; forever just on the horizon, only to arrive far too late as a complete disappointment. In order to salvage his ego, he could opt for inaction and pretend he could have succeeded if it weren't for those darn gremlins instead of actually attempting to do so and likely failing.
So we're probably in for a long, slow death with occasionally bursts of hilarity. Keep popcorn on hand as you never know when you might need it.
If he actively tries to Osana the kickstarter, then its assuredly dead in the water.
A kickstarter lives and dies on the community momentum and interest. Frankly, Alex hasn't had this much overall engagement on the project since like, 2017, or whenever the older youtube wave was. Its not good engagement, for the most part, but its there. You need to get that core audience hyped, interested, involved, engaged, and then ask them to open their wallets. You can't just wait a few years after all that momentum has faded, people have left, to then ask for a fuckton of money.
In my opinion, its frankly a mistake that he hasn't already launched the kickstarter, even with the demo problems. Having active fixing of issues for the kickstarter demo while the kickstarter itself is running would provide a facade of actual developer effort and determination. And giving the community consistently new builds and content to mess around with over the duration of the kickstarter would allow content creators to keep up a larger output over the duration of the campaign, as free callout to the rest of the internet.
He's already blown his big PR load, and if he goes into 2021 with no kickstarter, its over for that entire endeavour as it exists today. He'd have to create and hype another osana scale development goal, actually develop it, release it, get the same large "oh shit it finally happened" response, and then capitalize on that, while hoping that this failure doesn't reduce interest in the next effort. Hint, it probably will.
I'm not sure Alex's ego will actually prevent him from launching the kickstarter sooner rather than later. The Gremlins have been saying for years he'd never even make it to a kickstarter, so spite might drive him there, and his ego won't fear failure. His ego would consider a kickstarter failure to be an improbability.
