Hi All,
I have SharePoint list with around 4200 items and multiple Multiline text columns with documents uploaded on them.
I have multiline column (with NO attachement) and want to convert it to single line text.
i did try below steps and now none of our users (including me) cannot open this list.
1. Change multiline field to 'Plain text'
Actual issue
unable to open SharePoint list and error appears as below
