  1. Exit and relaunch the Steam client and check if the issue has been fixed.

Fifth Solution: Temporarily Disable Windows Defender

Windows Defender mistakenly blocks or puts files in quarantine, especially if the file is not yet in the safelist in the database of Windows Defender. This feature may cause the stuck Steam message saying “Allocating disk space,” although Steam and its associated files are legit and safe.

In this case, we suggest disabling the Windows Defender temporarily and while downloading the new game.

  1. Open Windows Defender by clicking on the Windows button and type “Windows Security” and press “enter”.

The stuck Steam message saying “Allocating disk space” is normal. What’s not normal is if it stays on the same message for a very long time. Remember that this happens when the allocation of the game file is disrupted, so make sure your disk has enough space to house the files, your internet is stable, and your anti-virus is not blocking any of Steam’s folders or files.
