Honestly, I have no idea what might be causing the error in your case, since it’s the first time I’ve seen it... Sorry about that. If you want, you can play the web version on itch.io, which is a reduced version, or the Newgrounds version, which is also web-based but complete: https://www.newgrounds.com/portal/view/1002421
I’ll keep investigating anyway in case I find a solution, and thanks so much for taking such an interest in playing StreamBound!
