Not able to add Group in Taxonomy manager

I am using UiPath Studio 2023.12.0. I have added Document Understanding related packages in the project.
UiPath.DocumentUnderstanding.ML.Activites: v1.24.0
UiPath.IntelligentOCR.Activites: v6.14.1

I am able to open Taxonomy manager but not able to add Group, Category etc. Text box is displaying but not able add text and save it.
I have installed .Net 5.0 desktop runtime components and also .Net 6.0 desktop run time components already but no luck.

Can you please help? Thanks in advance

Hi @hardik.doshi

Try Reinstalling Packages: Open Manage Packages in UiPath Studio, uninstall the Document Understanding packages (UiPath.DocumentUnderstanding.ML.Activities and UiPath.IntelligentOCR.Activities ), and then reinstall them. This can sometimes resolve issues related to corrupted installations.

or Try Reinstall UiPath Studio

Hope this helps!!

Thanks @irtetala for response!
I have uninstalled/installed package and also reinstalled the UiPath studio. But same problem.
