How to Fix Steam Won’t Open Issue

They can adopt the following steps for restarting: shutting down computer and router; then unplugging power cables from the router and plugging them back a few minutes later; finally starting router and computer to see whether Steam opens normally.

Fix 3: Close all the Steam tasks

How to check whether this problem is caused by the above reasons?

Step 1: Right-click Taskbar and select Task Manager.

Step 2: Find out all running Steam processes (including Steam Client Service, Steam Client WebHelper, and Steam Client Bootstrapper) and right-click them to select End task.

Step 3: Launch Steam again to see whether it opens normally.

Fix 4: Clear the app cache

The “appcache” folder in Steam directory is essentially used to store various data about Steam apps and setup. Each time players open Steam, it will remember the small details so as to ensure that next time the Steam things will work a little bit faster.
