todos demo in dev can not work

I use " npm init svelte@next my-app " to create the todos demo . but in " npm run dev" todos demo sometimes doesnt work :

In " npm run preview " sometimes have this error ：

my sveltekit version is next.119

I think it may be caused by the update. Because I have reported the above error every time after I update some code , and to recover it , I need to reinstall nodemodules

sveltejs / kit
