It was early OCT when I created the support ticket. no success despite many sessions and environment copies etc, until recently.
What I can confirm that there is a bug. Read the following: -
What has caused the problem is that in one custom Table, I created an image column, and set its field permission enabled.
Microsoft suggested that I delete that Table, was a hard time for me but I did. The new Table didn't have an image field anyhow.
I eventually have deleted the old Table (which enabling its image field security created the problem).
The problem would still exist.
I read online to realize that fields with their field security enabled are listed in a Table called Field Permissions. No access to this Table via the portal, I accessed it via Excel add in.
Weird enough the Image column that I enabled its field permission in the Table that was deleted, was still existing in the Field Permission Table.
I tried to delete that record, with no success.
After 6 weeks, I guided Microsoft to delete that record, was done, and then my system was working perfectly again.
I had a call from the Microsoft team manager to apologize, I said its fine, the whole year was hectic by all means. I only meant to guide the team behind of this bug.
Bottom line, do not enable field permission on image columns, I guess also on file columns
