First of all thank you for the great product! 💯 👍 !!!!

To Reproduce
Please include a code sample and launch.json configuration.
Steps to reproduce the behavior:

1. Create a .env file with a long environment variable. See attached file. envfile.txt
2. Add a launch.json using the .env file that runs any executable. See example launch.json.txt
3. Launch entry
4. See regrettable error message pop up on screen
   

Additional context
Problem occurs even if I set the environment directly in the configuration. It appears that the message is truncated on its way to the underlying engine.
The issue goes away if I remove one character from the attached envFile.

According to DevToolsSecurity -status, Developer mode is currently enabled.
