The problems I am experiencing began after a major Windows 10 update on the 23Jan 2018.
Basically, I have been using High Fidelity and Linden Lab Sansar which worked fine until now. The error you see in the attached image happens now every time I launch either viewer which then crashes.
I have tried a clean uninstall and reinstall and used Windows tools to clean & repair the OS but the problem persists and I am locked out of both services.
Any help for this would be appreciated.
