What's the problem with my password while installing Apex 20.1?

I am installing Apex 20.1 on my windows 10 with oracle 19c. After running the command : @apxchpwd.sql I get this error even after respecting all the password regulation and trying different combinations of mails and passwords :

User "ADMIN" does not yet exist and will be created.
Enter ADMIN's email [ADMIN] 
Enter ADMIN's password []
ERROR:
ORA-01756: quoted string not properly terminated
