Blank Page in New Email Account

I need assistance. I am unable to create new mailboxes in My ERPNext instance.

All I get is a blank page.

The issue also extends to the new email domain. I am unable to save any new email domains.

My Setup has:

Installed Apps

ERPNext: v10.0.18 (master)
Frappe Framework: v10.0.19 (master)
SendGrid Integration: v0.0.1 (master)

Hi @helios-ventures,

can you please check and share your browser console errors (F12, then console). This looks like an error when loading/rendering the page. Have you customised any fields or added custom scripts?

I have found the culprit, the problem was brought about by the send grid application. Once I removed it, everything is back to normal.
