Unable to Update from Monterey 12.3 to 12.5

Laptop Model: Macbook Pro 15inch (2018)

I used software update (under system preference) to try to update to 12.5 and failed every time. It downloaded for a period of time and then exited with some errors. Then I tried to use command line "softwareupdate -install -all" twice, and each time I got this:

% softwareupdate --install --all

Furthermore, every time I ran the software updater or command line updates, it seemed to download a new version of the update (thus taking up GB space quickly). Today, I ran 3 times in total and it's taking up almost 50GB of my disk space. Where is the folder which the installer files being stored? Where should I look to delete the installer files?

Any help with regard to solving the update problem and/or deletion of updater files would be much appreciated! Thank you in advance.

Correct myself - Apple Did Release a version 12.5.1 today. My Bad for earlier posting

Adjust the previous command to read below

softwareupdate --fetch-full-installer --full-installer-version 12.5.1

As for Why the update are not common down

There are factors:

1 - Like poor Wifi connection

2 - Slow wifi connection

3 - Too many other people downloading at the same time and Apple Severs are overloaded

4 - Software on the computer interfering with the download process including AntiVirus Software

Notation: Disabling the AV Software may or may not solve the issue. Removal of the AV Software may increase the chances of the download to perform as expected.

5 - Running behind a VPN which may increase Packet losses or corruption of the download

6 - If via wifi too many Other devices using the wifi at the same time reducing the Bandwidth to your computer.

7 - Best Results are via Ethernet Cable to Router

8 - Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal and Try Again using the Software Update Applet in System Preferences
