ERPNext v13.20 Education Domain Bug Not Working

Hi all,
This is regarding the latest update of ERPNext v13.20. I have installed the latest version of ERPNext and Frappe on my system yesterday after which I tried to run a complete cycle of education module but I am facing issue at the time of submitting the Program Enrollment. It says there is a date-time format issue in the field joining date, so I tried to trace back and found in the .py file there is a callback function which is not returning the appropriate date type format. How can I solve this issue.

I have the same issue. This has stopped work on my project. Has anyone found a solution?
I’m using mariadb 10.5…
