Expo crashes due to exceeding 80% CPU usage over 180s (iPhone 6s)

I’m developing an app on my iPhone 6s and this occurs quite often, causing me have to restart expo.
While running the expo app, my iPhone is stuck at 100% CPU usage.

Is there any way I can fix this?

The performance Monitor shows the following:
RAM: 300MB
Views: 2023 / 2571

Although I had to use a separate app to monitor CPU usage.

The following crash log was retrieved from the device using iTools
