while computing space requirements, it throws the error... no previous options since all i did was run the installer. i had a big hard drive on F: but it broke. i probably installed libreoffice on it before, and maybe it's checking to repair it or something.
Seems a problem with the OS. Searching on the web for 'windows 10 #1327 error'. Lot of results. One of them https://www.auslogics.com/en/articles/fix-error-1327-on-windows-10/ Which seems to hava useful information.
Closing as "invalid" for now, meaning this is likely unrelated to LibreOffice, but please set back to "unconfirmed" if you can rule out your hardware issues. Another link: https://windowsreport.com/error-1327-invalid-drive-p/
