Also during the package installation getting the peerDependencies warning:

astro is listed by your project with version 5.0.0-beta.6 (peec57), which doesn't satisfy what astro-purgecss and other dependencies request (^4.16.7 || ^4.16.7).

FWIW there are the following dependencies used in project (among others):

"@astrojs/tailwind": "^5.1.2",
"astro-purgecss": "^4.6.1",
"purgecss": "^6.0.0",
"tailwindcss": "^3.4.14",
