Issue Description:
I am experiencing a recurring issue where the spacebar stops functioning entirely within the lab terminal after approximately 5 minutes of use. This happens consistently across different labs, specifically within the “Certified Kubernetes Administrator (CKA) with Practice Tests” course.
Symptoms:
The spacebar works perfectly for the first few minutes of a session.
After ~5 minutes, the spacebar stops registering in the terminal (both in the shell and within vi insert mode).
Other keys continue to work normally.
Opening a new tab or restarting the lab provides a temporary fix, but the issue returns shortly after.
Environment Details:
OS: macOS Tahoe v26.3 (Apple Silicon/arm64)
Browser: Chrome Version 145.0.7632.117
Access Method: Udemy/Subscription
Troubleshooting Already Attempted:
I have followed the standard troubleshooting steps provided by support, including:
Logging out and back in.
Testing in Incognito/Private mode.
Clearing browser cache and cookies.
Disabling all browser extensions.
Verifying keyboard input methods/language settings.
Testing on different networks.
Despite these steps, the issue persists. I have also seen a similar issue reported previously here: Space in the Lab
Has anyone else encountered this specifically on macOS or the latest Chrome builds? Any advice on a permanent fix would be appreciated, as this makes completing timed mock exams nearly impossible.
