After a full rebuild, installed new drivers ect... on Dell laptop, Skype for business keeps crashing with the following errors.

Has anyone else had these issues, if so what could be the fix as the error message given does not look like it is linked with Skype.

Skype for business seems to crash every time i receive a phone call, thus unable to answer.

When IM'ing it works fine, but its every time i receive a call.
