battle error, specific wild pokemon frozen and cannot continue the battle

whenever i battle specific wild pokemons like sandshrew they just freeze up and does not make a move and i cant continue the battle, i have to run away to get out of battle

the pokemons i fought recently that had this bug was ampharos,sandslash,sandshrew and arceus from pokemans addon and it happens when i fight them out in the wild or i encounter them in a gym,they also dont dissaper in the wild if i run away like the other pokemons do

im using fabric and cobblemon ver 1.6.1

other mods i used are cobblemon mega showdown
