Symptoms

Game does not install on BTRFS based distributions due to case mismatch of folder names in the installation depots.
Installation fails at 99% with "Disk Write Error"

Specific mismatch in:
SteamLibrary/steamapps/downloading/1338770/Localization/english_xml.pak

meanwhile the download/installation process creates:
SteamLibrary/steamapps/downloading/1338770/localization/

Difference being the capitalization of /localization/ folder.

Manually changing the capitalization to uppercase L allows the installation to complete.

Reproduction

• Try installing the game on distro such as Bazzite and BTRFS formatted drive.

• Observe "Disk Write Error" at 99% download/installation

• Check steam content_log.txt

• Notice lines:

• Rename the folder to uppercase L.
