You may see a red screen in a simulation if you have limited free memory on your laptop. To fix this, here are the recommended options:
Option 1: Try Chrome Instead
Try the Chrome browser instead. It handles memory better than other browsers.
You can download it for free here.
Please note that Safari is not currently a supported browser.
Option 2: Check minimum requirements
Finally, if you still experience the issue, it may be because you have less than 4GB of memory on your laptop, which is one of the minimum system requirements for using Labster. Please check the page above, to make sure you use a laptop that meets the minimum requirements.
Please do not hesitate to reach out to our support team if you have any questions or are in need of assistance.
