We’ve been noticing a rash of “Medium: Failure to Start” reports. After an investigation, we’ve found that sometimes Vulkan, a fairly new graphics API we started using with 2.0, will fail to initialize and cause Medium not to start.
Most of the time, the failure to initialize is due to an out of date graphics driver issue. The normal driver upgrade process doesn’t always reliably resolve this problem: the drivers are corrupt, or the install didn’t do so correctly. To amend, we recommend a manual upgrade process following the instructions below:
