Cant close/edit/add/assign to another tech on 1 log

Hi there I have a log that I need to close, but when I click on close, it takes forever then eventually brings me into the edit call screen.

I try to close it here & it fails again.

I cant assign it to another technician, no other technician can close the call or edit it in any other way.

Its extremely frustrating....

Can anyone help?

Cheers.
