RStudio crashing when launched

Error Information:

Description of issue - RStudio suddenly crashed during startup today despite working fine every day in the last several months. Please see screenshot of the error. I noticed that 64 bit R (for instance, RGui) was crashing too, but the 32-bit R worked fine.

Attempted steps taken to fix - Tried uninstalling/reinstalling both R and RStudio. Also tried resetting RStudio's state as recommended here. Neither RStudio nor 64-bit-R worked. I have also been unable to connect RStudio with the 32-bit-R installation
