This seems to be an upstream issue.
rollup/rollup#4496

+1， i have same problem。

after debugging, I found that it is caused by the following code

at 'rollup/src/utils/options/normalizeOutputOptions.ts'

...
preserveModulesRoot: getPreserveModulesRoot(config),
....

const getPreserveModulesRoot = (
	config: OutputOptions
): NormalizedOutputOptions['preserveModulesRoot'] => {
	const { preserveModulesRoot } = config;
	if (preserveModulesRoot === null || preserveModulesRoot === undefined) {
		return undefined;
	}
	return resolve(preserveModulesRoot);
};

but, at ''src/chunk.ts" 中

const currentPath = `${currentDir}/${fileName}`;
const { preserveModulesRoot } = options;
if (preserveModulesRoot && currentPath.startsWith(preserveModulesRoot)) {
	path = currentPath.slice(preserveModulesRoot.length).replace(/^[\\/]/, '');
} else {
	path = relative(preserveModulesRelativeDir, currentPath);
}

currentPath not resolve， but preserveModulesRoot had resolve， so in windows platform，currentPath.startsWith(preserveModulesRoot) always be false。

This is due to vite normalized the slashs while rollup leaves it platform-dependent. See the complete comment here: rollup/rollup#4591 (comment)

This issue is fixed in rollup 2.77.3
