On-premise Vivado 2017.4 crash on windows 10

While running a build, I got the error "EXCEPTION_ACCESS_VIOLATION". I checked the log pointed to by the message and it was empty. I closed Vivado and restarted in a fresh directory. But this time, Vivado crashed, just disappeared without any warning or message. After this, I tried multiple settings, and even recompiling some old projects which have been compiled successfully many times before,but Vivado just keeps crashing. The Vivado is starting to execute the synth_design task when this happens.In last compilation, the last message in Vivado log before it crashed was:

Launching runs with argument(s) impl_1 -jobs 20
INFO: [IP_Flow 19-4838] Using cached IP synthesis design for IP cl_clk_wiz_0_0, cache-ID = e74bb25c0f1c1add.

I am using Vivado 2017.4op on Windows 10. Has anyone else seen this crash? Are there any known workarounds or fixes for this.
