Just bought Razer Blade 14 2023 and experienced problem with Synapse 3 software - it hangs and do not open control panel with Razer Blade configuration (see picture). 
This bug totally kills your laptop mobility - because you are unable to change laptop performance mode and in high performance it works 2-3 hours.

All potential fixes on internet did not helped
1. tried full reinstall/restart synapse 3 several times, did not helped at all 

2. found some fixes with disabling "Fast boot" option in Windows Power Management System - unfortunately did not helped me, but turns out it helps in some cases

3. factory reset of laptop and disabling any updates on windows or drivers - allowed to launch Synapse first time, but on the next system boot Synapse updated to latest version (without asking any permition) and after this did not launched Razer control panel

4. all drivers, windows updates, synapse is up to date

There is quite a lot of questions with this issue on the internet, but no official comment or fix.
