Thanks I have fixed the error.
Viewing post in City Jumper jam comments
I got another error!
" Data folder not found
Application folder:
D:/Downloads/MNG/Builds
There should be 'City Jumper_Data'
folder next to the executable
"
But I renamed The Mix and Game Jam_Data folder to City Jumper_Data, and it ran! Seems like the character moves really slowly though, maybe this is because of my hacky fix :)
