With Redmine 6.0.9 I get the same error. This seems to be a conflict with the "Products" plugin from RedmineUp. I am not sure who is wrong here (or if there is even a "wrong"). I was using both plugins together on Redmine 5.1.10 already. When upgrading to Readmine 6.x, I also had to upgrade the Products plugin.
I have upgraded from Redmine 5.1.x to Redmine 6.1.2, but the datetime_custom_field gives me an error when trying to open the "My page":
