DB Error while saving the Form page of while creating a new application.

Hello Community,

I am a new bee with here and not much familiar with Creatio Studio as well. I have created a demo environment of creatio studio from downloadable. I created a new application where I am creating a list and detail page. 

The issues I am facing are:

• The list view page shows that its continuously loading, because of which I am not able to hide or create a new column which is obvious.
• on the Form page when I try to save my form elements/objects It is showing an error as Failed to update the structure for following schema and the schemas are my form objects which I am trying to save.
• I found one solution on the community here that by updating the objects showing error on Workspace explorer page (System designer->advanced settings->configuration. I see my objects showing error in the status column. I did try updating the DB objects from there but showing the DB error. I think the above issue and this one is related and due to the same reason(Screen shot2)
•  When I try to compile all in configuration, I get an error. (screenshot 3) I tried uninstalling and reinstalling the SDKs(The solution again I found here) but it doesn't seem to be working for my case.

I really Appreciate if someone could help me to figure this out.

Thanks
