Hi!

I think this could be fixed by #3245 but it wasn't released yet to autoload for everyone.

Can you change your <ClerkProvider> inside your Next.js application to the following?

<ClerkProvider clerkJSVersion="5.2.3-snapshot.v47a3ff9">

And then try again? This would be a temporary test of the new version to see if it works.

#3245 was released now. Please retry again with latest versions.
