Core and Extensions Are Extremely Slow to Load

Versions

Autorest version: 3.0.6187 Node version: 12.18.1 @autorest/core: 3.0.6302 @microsoft.azure/autorest.csharp: 2.3.82 @microsoft.azure/autorest.modeler: 2.3.47 OS: Windows 10

Current Behavior

Any command including the --csharp flag spends multiple minutes sitting with the output

(C) 2018 Microsoft Corporation.
https://aka.ms/autorest

Once this extremely long wait is complete messages for the modules loading are printed, following quickly by the output for the actual command.

This behavior occurs even when running the command autorest --csharp --help

Expected Behavior

Loading these modules should only take a few seconds, which was the case for me in the past.

I think it is possible the issue @finalcut is experiencing may be different from what I am seeing. Like I said, I see this even when running this command, which has nothing to do with generating any code:

autorest --csharp --help

I just tried running that command with the additional flags, but it looks like the timing starts after the long wait. The output suggests that this took 5 seconds, but it was actually multiple minutes. The time spent waiting is entirely between https://aka.ms/autorest being printed and the next line appearing.

autorest --csharp --help --debug --verbose

Core Settings and Switches

  --help                        display help (combine with flags like --csharp to get further details about specific functionality)
  --input-file=<string | string[]>  OpenAPI file to use as input (use this setting repeatedly to pass multiple files at once)
  --output-folder=<string>      target folder for generated artifacts; default: "<base folder>/generated"
  --clear-output-folder         clear the output folder before writing generated artifacts to disk (use with extreme caution!)

Core Functionality
   While AutoRest can be extended arbitrarily by 3rd parties (say, with a custom generator),
   we officially support and maintain the following functionality.
