Any way to undo swupd repair?

Hi, i usually run swupd repair after updating Clear Linux. But i got one corrupt file

Repairing corrupt files
 -> Hash mismatch for file: /usr/share/gdm/env.d/flatpak.env -> fixed

it seems that other application or flatpak itself change the content. and swupd repair change it to default because the hash is mismatch. I don’t know what affected after this repair, so i just wanna see the previous file before swupd repair just to be sure it is fine.
