Loading the OptiX Ray Tracing backend fails silently in v5.7.0 RC2
If creating the VisRTX context fails (e.g. if VisRTX is not able to find the OptiX libraries), ray tracing will fail silently. Ray tracing can still be enabled via Python or the checkbox in the client, but the data will just disappear with no warnings or errors. A warning/error message would let the user know that there is a problem with their environment configuration.
