Blackwidow v4 Pro startup and chroma lighting issues

Good morning Team Razer. I am having issues with my Blackwidow v4 Pro keyboard at startup and with the Chroma RGB. Right now from a cold start I can tap the keys and the computer will wake from sleep but the keyboard itself will not start and I am unable to type unless I remove the wrist rest and reconnect it. The keyboard lights up after this and I am able to start typing, however the Chroma lights will shut off after a few seconds of being logged into the computer, but the typing still works. I reviewed a previous post (Answer ID: 538) and followed all the instructions listed there and that seemed to work for a moment, and then with the latest Razer update that no longer seems the case. Reviewing a few other threads, I found a solution of turning off the dynamic lighting setting on Windows 11 fixed the issue, but as I am currently running Windows 10 and cannot upgrade due to a processor incompatibility I do not seem to have this setting and therefore cannot fix the issue. Any info that can be provided to correct these issues will be most appreciated. Thank you!

Disregard, I think I managed to fix the issue by uninstalling and then reinstalling Synapse. Followed the instructions for clean reinstallation and only reinstalled Synapse and not the Chroma apps. Seems to be working for the moment but I will reach out if there are any further issues!

Chroma lighting now working again but I am also still experiencing the issue of the keyboard itself not starting up unless I disconnect and reconnect the wrist wrest. Power management for the Root Hubs under Universal Serial Bus Controllers are all unchecked for “Allow the computer to turn off this device to save power” and under Power Options “Never” is selected for Sleep>Hibernate after. Any further info is most appreciated.
