Thanks Carl! Please read my initial report and define “CRASHES” please. The Mac fan has a fast rush and the Mac crashes, reboots and produces a crash report hence my comment “crash”.
Hello KIG16F,
It's very important to ensure your Mac continues to work as expected after disconnecting an external monitor. To clarify, is the Mac powering off, or does the Mac remain powered on just not show anything on the display?
If the Mac is remaining on are you able to adjust the display brightness as outlined in the following article to get the display back on?

Hello KIG16F,
Thank you for clarifying upon the issue you're facing as crash can define a variety of issues. With the Mac unexpectedly restarting when disconnecting the monitor it is recommended to confirm that macOS is updated. If macOS is updated, and you're disconnecting the monitor without exiting target display mode you may would want to exit target display mode to notate if the issue happens that way, then attempt the following steps.
