After the most recent update (version 1.3.0.157), my Arma Reforger in-game mod manager has completely stopped downloading any mods, regardless of size or number of dependencies. I have tried all known troubleshooting steps without success, including:

Verifying game files through Steam

Clearing the Steam download cache

Completely uninstalling and reinstalling the game

Deleting all mod-related directories, including:

%localappdata%\ArmaReforger\

C:\Users\[Username]\Documents\My Games\ArmaReforger\

Steam\steamapps\workshop\content\1874900\

Disabling Steam cloud saves

Checking firewall and network settings

Running Steam as administrator

Attempting downloads on multiple network connections

The error persists regardless of the mod being downloaded, and the issue is not related to disk space or drive formatting. This problem seems to affect every mod, including popular ones like RHS - Status Quo.
