I have run into a similar problem when upgrading to 23.05, and solved it 
by running queries like this directly in the database:

mysql> update circulation_rules set rule_value = '0.00' where rule_value 
= '0,00';

If you have this problem with other numbers, repeat the query but 
replace 0,00/0.00 with the other relevant numbers.
