[Linphone-developers] [ZZLC-973445]: Fwd: Blank GUI window when answering a phone call (non video)

[TNS IT Support]

Hi there Linephone team. 
We are the IT company that, installed and maintains the client in question, who are experiencing the blank GUI.
What are the next steps in order to fix this issue?
We were going to uninstall and reinstall the application, but like the client has mentioned, they have contacts that they do not want to lose, and I cannot see a way to export the contacts on linphone, unless I am missing something.

Thanks 

Adam
