To fix this bug, need to change line 69 from page.lastUpdated -> page.lastUpdatedTimestamp.

vuepress-plugin-sitemap/index.js

Lines 68 to 70 in f3648c3

	const lastmodISO = page.lastUpdated
	? dateFormatter(page.lastUpdated)
	: undefined

Explanation

    lastUpdated: '21.5.2023, 23:13:40',  // Cannot be parsed by new Date(...) -> Invalid time value error
    lastUpdatedTimestamp: 1684700020000  // Can be parsed new Date(...) ✓
