Why do the NI VISA drivers (v20) crash on macOS and fail to load as a dylib?

UPDATE: I read the release notes on V20 and apparently MacOS 11.x is not supported yet.


I recently installed the NI VISA drivers (v20) on a MacBook Pro (2019) with Big Sur.


The NiMAX application crashes, and the VISA framework fails to load with various permission errors (usually related to RAID or highpointRR).


I can't pinpoint the exact date, but last year on Catalina with V19 drivers everything worked fine.


The NiMAX program pops the main window, then quits unexpectedly with a Problem Report window.


Compiling a simple C program to link to the 'visa.framework/visa' dylib results in:


"Error Domain=KMErrorDomain Code=71 "Insufficient permissions for action: Unable to load 'com.highpoint-tech.kext.HighPointRR' in unprivileged request." UserInfo={NSLocalizedDescription=Insufficient permissions for action: Unable to load 'com.highpoint-tech.kext.HighPointRR' in unprivileged request.}
Abort trap: 6"
