Internal Server Error on Cloudflare with @sveltejs/adapter-cloudflare from v7.1.0 #3157
Description
Describe the bug
From the version 7.1.0 of @sveltejs/adapter-cloudflare, using the svelte-loader library returns a Internal Server Error 1101 on Cloudflare.
Version 7.0.5 works fine.
See this issue I made for further detail. I clearly identified that using this library causes the issue:
sveltejs/kit#14027 (comment)
As stated by a Svelte maintainer, the major change since version 7.1.0 is this:
The biggest change to the worker was in https://github.com/sveltejs/kit/pull/13859/files#diff-9956f0811d38fc2939d554ee334ccda62ba5c4697329b42d20d304730b0c0304 which moved the server initialisation outside the fetch handler and passes instances of env to the server at the top-level. Therefore, it might be worth checking if there's some logic in the init hook that's trying to access env. However, we might need to move it back into the fetch handler so that code inside the hook can access bindings
Workers do not allow I/O from outside a request context. This means that even though env is accessible from the top-level scope, you will not be able to access every binding's methods.
For instance, environment variables and secrets are accessible, and you are able to call env.NAMESPACE.get to get a Durable Object stub in the top-level context. However, calling methods on the Durable Object stub, making calls to a KV store, and calling to other Workers will not work.

A workaround, found by Sonnet 4, is to not import the server client at top level and instead use it in a SvelteKit hook handler with async import. This seems to do the job but this is not ideal. It should work how it's supposed to be from the README file.
To Reproduce
Use SvelteKit using the Cloudflare adapter v7.1.0+ and the svelte-loader library
Expected behavior
It should act the same from v.7.0.5 to 7.1.0+
