Type of extended Prisma client is too long (TS7056)

Hello, I am currently trying to install the following extension in my Prisma environment. https://github.com/yxx4c/prisma-extension-redis 
// It is not possible for Typescript to create the type for extendedClient
const extendedClient = (prismaClient: PrismaClient) => {
  return prismaClient.$extends(PrismaExtensionRedis({ config, client }));
};
type ExtendedClientType = ReturnType<typeof extendedClient>;
// It is not possible for Typescript to create the type for extendedClient
const extendedClient = (prismaClient: PrismaClient) => {
  return prismaClient.$extends(PrismaExtensionRedis({ config, client }));
};
type ExtendedClientType = ReturnType<typeof extendedClient>;
Unfortunately the typing of Prisma causes problems at this point. Typescript tells me that the derived/combined type from Prisma and the extension is too long (TS7056). 
error TS7056: The inferred type of this node exceeds the maximum length the compiler will serialize. An explicit type annotation is needed.

Is this a known bug when using $extends?

Incidentally, this does not refer to the extension I linked. This behavior currently occurs with all larger extensions. I have the feeling that it has something to do with the size of the Prisma schema and the size of the type generated from it.

I was able to find a related GitHub Issue here: https://github.com/prisma/prisma/issues/16536 But that seems to be fixed. Is this happening on latest prisma version? Do you get this error if you try to use other extensions as well?

Yes, I'm using Prisma 6.5.0 and it happens also with other extensions. I've also seen the the linked issue but unfortunately it's not an option to deactivate the declarations. Do you have an idea how this could be fixed?
