Issue/Introduction

When attempting to update project finish date on any project we are getting error 500.

We could not save projects finish date with any dates greater then year 2031, so 2031 is saving, but 2032 is throwing an error.

ERROR Error 500 - Internal Server Error. The server could not retrieve the document due to server-configuration or other technical problems. Contact your site administrator.

I have cheeked the last updated by column and it is 1,  I also tried to login as multiple users and issue with all users.

Does anybody know what could be the reason?
