Nope, working flawlessly for me.

What is do you have exactly? Win 11 24h2 ? 23h2?

Did you've tried to reinstall it (remove and install as administrator).

nah, i already reinstall it many times and still have the same problem, i started install synapse 3 and it can’t work too

Did you’ve changed the temp location in windows? Also what’s your exact windows version (you didn’t answered previous question completely).

Also you can try doing clean reinstall Synapse with these steps:

1. Uninstall Synapse
2. Download & run this tool: https://rzr.to/Tf53xj to remove any razer drivers/leftovers
3. Check %appdata% folder for any leftovers associated with Razer like razerappengine for eg. If this folder exists - delete it.
4. Then restart your PC
5. After reboot install Synapse again (as administrator).

Oh sorry, i am using windows 11 Pro 23H2 version, and i already tried ur method with downloading that tool. but still the same, the synapse kept saying javascript error. please help me...

And when i’m running my synapse 4 it will double pop up for the administrator notification

Dunno what to recommend next, sometimes it’s just OS fault I don’t know your exact environment. But you can submit a case with Razer Support: https://mysupport.razer.com/app/warranty-support/
