Unexplainable "Resolving Shell Environment is Slow" warning and error

Issue Type: Performance Issue

I am running KDE on Linux with zsh. When starting VS Code via the Applications menu or KRunner, I get the "Unable to resolve your shell environment in a reasonable time" error. According to https://code.visualstudio.com/docs/supporting/faq#_resolving-shell-environment-is-slow-error-warning it means that running my .zshrc is taking more than 10 seconds.

However, starting up Konsole takes up less than 2 seconds from the moment I click on the icon to the moment that I get a shell prompt. What is VS Code doing that Konsole is not, that it takes more than 10 seconds to run my .zshrc?

Also, I really can't remove anything from .zshrc (I need it for actual terminal sessions). Is there a way of determining whether .zshrc is being executed by VS Code so that I can conditionally enable/disable parts of it?

VS Code version: Code 1.53.2 (622cb03f7e070a9670c94bae1a45d78d7181fbd4, 2021-02-11T11:48:44.518Z) OS version: Linux x64 5.8.0-43-generic
