rollup is watching C:\ in windows environment, if dynamic imports are used

[HerrDietz]

Describe the bug

I'm not totaly sure if I'm on the right track here:

We noticed the node process terminated regulary when we ran our script for vite in watch mode (vite build --watch) after migrating to vite 3.x.
We are under the impression, that if you use dynamic imports in an windows environment, rollup is also watching C:\. This seems to lead to the error.

Sadly, the termination is not deterministic. At some point in time, after a change, the process just craches. I suspect the build time has something to do with the crash: longer build times seem to favor an error.

After digging into rollup, we noticed that at some point the path /@vite/dynamic-import-helper is watched. Somehow, this path is 'translated' into C:\ in my Windows environment.

I created a breakpoint in node_modules\rollup\dist\es\shared\watch.js in async _addToNodeFs(path, initialAdd, priorWh, depth, target) in line 3184

This does only happen if dynamic imports are used.

I am not entirely sure if both behaviors (watching C:\ and crashing) are related.
