The game stay forzen

I just checked and doesn't seem to affect newly created games.

Eh I think I solved, although Im not sure what was the solution, first I though that the event may be the cause so I changed the event from automatic to the summer carnival, then opened the game again to see if it works and yes it started to run normally, then I started to think what could be the reason and noticed that my rocky biome was empty because I had mined all rocks there so I thought that maybe one of the kitties were trying to spawn there but it couldn't for the lack of rocks so I bring a boulder from the caves to the biome, closed the game, activated the year of the catcoon again an started the game and this time it didn't froze, the kitty wasn't in the boulder but the game seems to work now.

Glad you were able to figure out a solution
