Omnisphere loading issue on M1 Mac

I am working on a Nuendo 12 project with several virtual instruments on an Intel Mac Pro (Mojave). On my MacBook Pro M1 (Monterey) -which has the same instruments installed- that same project refuses to open the Omnisphere instance, stating it can’t be loaded. However, it is possible to add a new instance of Omnisphere without any problems. How strange is that?
