Cloudflare Workers Failed to run --remote preview

Hai My sveltekit api runs noramlly when i run

npx wrangle dev

npx wrangle dev

But shows something like this

"Error: internal error; reference = 4lrskvh59d8cvjp6e5550i74a
    at async Object.fetch (file:///D:/example/sss/ssss/node_modules/miniflare/dist/src/workers/core/entry.worker.js:4321:22)"

"Error: internal error; reference = 4lrskvh59d8cvjp6e5550i74a
    at async Object.fetch (file:///D:/example/sss/ssss/node_modules/miniflare/dist/src/workers/core/entry.worker.js:4321:22)"

While running

npx wrangle dev --remote

npx wrangle dev --remote

Cant exactly find the solution / cant even undertand whats the problem is 📌 ✔️ Note : When i Deploy it works Perfect only problem when running

npx wrangle dev --remote

npx wrangle dev --remote
