Unfortunately I'm having issues with joiplay as well. Crashing on launch. I used the exact links given and the tutorial as well with no luck. It worked with the prior version just fine for me! Using s23.

As i said in an other comment, my suspicions were correct. Patreon version 0.14.3 does not give this error with Joiplay. Look for it in F95Zone, I played that one with Joiplay and it doesn't give any error.
the problem seems to be in the Public Version because the "fixed bugs" and "The French Translation". But i guess the real problem is that the public version has a upper version of RenPy that is not supported by Joiplay yet.
Itch doesn't allow to post links from f95zone, but you can google it.
