Razer Syanpse 4 and Chroma app installed but on launch both fail

I’ve installed the new Razer Synapse 4, both Synapse and Chroma app are installed

However, trying to launch them I got a failure.

Synapse, Installation failed:

Chroma app: failed to start


Troubleshooting steps already done:
- removed the old Synapse app
- cleared the program folder and registry entries
- deleted the windows service (it’s not listed anymore)
- rebooted the pc
- installed the app from scratch with admin rights

It’s a windows 10 computer, and I’ve a Razer Cynosa Chroma keyboard, that should be supported by Synapse 4 accordingly with the FAQ page.

How can I have the app working again?
