I have the following issue:

After upgrading @sentry/integrations from "7.81.1" to "7.114.0" we noticed a large performance regression. The app was taking a long time to respond to a user's tap.

Before (@sentry/integrations 7.81.1)

RPReplay_Final1721856524.MP4

After (@sentry/integrations 7.114.0)

RPReplay_Final1721856599.MP4

When we enabled Sentry in dev, we saw a bunch of logs that were clogging up the console and were able to reproduce the unresponsiveness locally. I've uploaded a video at #3963 (comment)

Steps to reproduce:

• Enable captureConsoleIntegration integration
• Try navigating around the app

Actual result:

App is slow to respond to user's tap.

Expected result:

App navigates as normal

@yefim thank you for the detailed report and the videos, we appreciate the effort. Do you know if this also occurs on Android, or only on iOS?

Yes, seeing the same against Android in development.

Here's the code diff:
