Bug with Terminal and global environments

After restarting macOS opens Terminal app (which was opened before a restart). And Terminal ignores all custom global environments.

This bug exists in Big Sur and Catalina.

If close Terminal app and launch manually everything is OK.

I write custom global environments to environment.plist file which is placed in user's home folde > Library > LaunchAgents

and then loaded:

Code Block 
launchctl load /Users/myprofilename/Library/LaunchAgents/environment.plist 
launchctl start /Users/myprofilename/Library/LaunchAgents/environment.plist 

I need custom global environments to set a variable to my working directory which is used in compilation scripts.
