React-Native/XCode/iOS Simulator – os/kern No Space Available Error

Introduction/Problem Replication

I encountered this issue with my react-native project, and decided to use a brand new project straight from the react-native site to try and fix the issue.

Problem:

I pod install, my build configuration is set to Debug, and whatever else was needed to get the build up and running.

The message "Build Succeeded" pops up with no errors. But then I receive this (os.kern) no space available error.

Visible Error Message Here

Error Details:

(os/kern) no space available
Domain: NSMachErrorDomain
Code: 3

What I use:

My Computer: iMac Late 2015

OS: macOS BigSur 11.2.3 (Build 20D91)

Available Memory: 200GB

XCode 12.4 (17801) (Build 12D4e)

What I’ve Tried:

• Issue started in Catalina, decided to upgrade BigSur to see if it
  would alleviate issue. Issue persists.

• Tried both processes on bash and zsh terminals. Issue persists.

• Tried with other react-native projects. Issue persists.

• (Possible Solution?) Attempted to use the command npx react-native run-ios, installs the app on the simulator but ends up crashing on the storyboard. Still issue persists.
