Razer Synapse Won't Open? Here Are 5 Ways You Can Fix That
Razer Synapse provides users with an easy way to rebind controls and configure macros to Razer's peripherals, such as keyboards, mice, controllers, and headsets. Unfortunately, sometimes users run into a problem with Razer Synapse 3 failing to start. This article is dedicated to helping you fix this issue.
Razer Synapse works fine right after installing it for many users, but the next time they log in to their account and the software starts syncing their settings, the application fails to open.
The program opens the login window, but upon logging in, it closes. The program continues running in the background, which can be seen in Task Manager, but users can't open its user interface.
How to Fix This Issue?
One of the ways you may fix Razer Synapse not responding or not working is by completely removing it from your PC and then reinstalling it. Some users have managed to resolve the issue by running the software as an administrator.
Others solved the issue by creating a new Razer Synapse user account. The new account won't sync any settings, so it won't get caught up with any issues. Yet other users have managed to fix the issue by manually deleting Razer folders from Program Files and Program Data.
On a side note, if you're having a similar issue with the legacy Razer Synapse 2, then try reinstalling the program, and when prompted to install Synapse Surround, click Cancel to prevent it from installing.

Solution 4. Perform a Clean Razer Synapse Installation
Reinstalling Razer Synapse is an effective way to fix the program not opening. Reinstalling it will replace all of the files that might have been corrupted for one reason or another. However, simply running the uninstaller and reinstalling the program might not be enough.

Solution 5. Create a New Razer Synapse User Account
Some Razer Synapse users have suggested creating a new account may fix the problem, at least temporarily. However, to do this, you will also have to create a new email address as you can only have one Razer account per email address.
1. After performing a clean installation of Razer Synapse or logging out of your account, click Sign Up.
2. Type in your new Razer ID and enter an email address not associated with Razer Synapse.
3. Then, type in a new password and click Start.
