[bug] Edge Runtime Compatibility Issue: "Class extends value [object Object] is not a constructor or null" with reown app kit

Summary

When running my Next.js app with Edge Runtime enabled (i.e., using export const runtime = 'edge'; in my pages), I encounter the following error during runtime:

TypeError: Class extends value [object Object] is not a constructor or null

This error appears to originate from code in the reown app kit package (or one of its adapters). When I disable the Edge runtime (removing export const runtime = 'edge';), the app runs correctly under next.js.

I expect that reown app kit and its adapters work correctly with the Edge runtime. Is this a known issue, or is there a recommended workaround or configuration change to resolve this error when using the Edge runtime?
