Excel Message [Unhandled exception stack shown on Excel startup]

Hi,
I am excel user and from couple of days I have been promptet with this message everytime I open excel. I have restarted my computer, but I still get this message.

I want to ask if anyone is having solution?

I have attached screenshot of the error message.

Well after clicking OK I have no problems using excel, but I dont think it is normal. I dont think it is an addon problem.

And the "Sign in" is coming from excel. It is the to log in to use excel in collaboration.

Go to File > Options > Add-ins and see what add-ins are listed.

Also, what kind of collaboration do you mean? I have never seen a scenario where Excel prompts for a login just because you open it.

Well the Sign in appears on every computer, for version 2013 and 2016, the window on the first image was just too small and cramped.
This is an image with my addons and a proper view of excel.
