I have a hard time finding anyone interested on working together. I think there is a lot of people who seem very enthusiastic about working on a project then when the actual work part comes up they find out they really don’t want to do it. Like they fell in love with the idea but were not prepared to do the work to bring it to life once they found out it IS actual work lol.
My advice is to find people and create a discord or something that is private where you and similar people can communicate. From there it might get easier. A lot of the bigger communities and discords are just to crowded to ever find what you are looking for and surely rules and other things will get in the way. Best to make your own small community if you can.
