Hi Nahid Jawad Angon,
First of all if you want to select only one record then you should use many2one field instead of many2many and if you use many2many purposefully then you can write constraints on that field like below.
Find code in comment.
I hope this will help you.
Thanks & Regards,

Code :-
@api.constraints(user_ids)
def check_user_ids_lenght(self):
if len(user_ids) > 1:
raise usererror("Please select only one record for this field.")
Thank you
Thank you
