Describe the Bug

Using the new app folder with the plugin swc-plugin-coverage-instrument breaks.
I get the following error when trying to visit a simple index page:

error - (sc_server)\node_modules\next\dist\shared\lib\app-router-context.js (10:40) @ eval

It's possible to avoid the problem by using babel (with babel-plugin-istanbul) instead of swc or by staying with old pages instead of the app folder.

Expected Behavior

The index page should load

I did a quick try and looks like this is not a next.js upstream bug, more of a bug in the plugin. Probably, this issue can be closed.
