Version 15 assets missing after bench setup requirements and bench build

Thanks everyone I already managed this issue by adding css name that are missing

May I know how did you manage to add the assets?

Please tell me the solution with some details, I am also facing the same problem

Simply fixing permissions worked for me:

 sudo chmod -R 755 /home/frappe-user/
 sudo chown -R $USER:$USER /home/frappe-user/

Also ran production setup to be sure

 sudo bench setup production frappe-user
