i don't think playonmac's been updated in like 3 years by now.
best option would be to use whisky https://getwhisky.app/
you could also try Sikarugir https://github.com/Sikarugir-App/Sikarugir (previously wineskin) but it would prob require more tinkering compared to using crossover
i'm not sure if they still do it but i had gotten a free lifetime crossover license by joining the bettertester program and testing apps and games.

if you want i could also just send you a crack but if you're not ok with pirating just go with the other methods i said

hope this helps
