Unable to add new lookup table to project post upgrading to 22.1.19 version

We upgraded Pega Soution containing multiple projects from version 19.1.125 to version 22.1.19 , post which we are unable to add new lookup tables to Project as it shows “Object reference not set to an instance of an object.” error while trying to edit field name.

@AswathiK16587086 I suggest you to update to version 22.1.28 and see if you can replicate the issue. There are couple of issues resolved for lookup tables after 22.1.19 version release

@AswathiK16587086 I am not able to replicate this behavior with 22.1.19. I suspect something else is the issue here. I would need to take a look at your solution. Perhaps the StudioLog might show what the issue is. Are you able to reproduce this in a new solution?
