Greetings! I also wrote to the support of the Razer company, so far they haven't found a solution either, so I thought I'd post it here, maybe you can help me.

When I bought the Razer Deathadder V3 (mouse), I didn't have any problems, that program was automatically installed via USB when I plugged it into my computer. It worked great all the time. However, one day I entered Malwarebytes for no reason to delete some nonsense, and when I deleted something (which has nothing to do with Razer), after that the application did not want to start and kept throwing out an error. Now, it may not be that, but he mentions Java to me and I no longer understand what it is about. I must mention that I uninstalled and installed the program several times, I deleted all the live (Razer) folders on the computer, again nothing. I'm losing my patience. I installed Razer Synapse 3 after that, it works great, but that software's support ends in January next year, I want to update. So, if you know anything related to this, please help! I will be at your service to answer whatever you need for the future.Screenshot 2025-07-30 225446

    Hi! If this started after the Maleware bytes actions, try this:

    • Open Malwarebytes > Detection History > Quarantine and restore any entries whose path starts with C:\Program Files (x86)\Razer\ or C:\ProgramData\Razer.

    If this fails, please try to restore your device to a previous state before the Malware bytes actions:

    Sure, have you followed the steps in the link as mentioned, that should help to do the system restore, or you mean you didn’t have it active?

    Then I would suggest to do a system reset cause that would be the easiest, but I do thing you need to keep in contact with Razer support as the are the ones that develop the apps so they should have better knowledge about the issues and how to solve this

    Malwarebytes probably flagged one of Synapse’s background service files as suspicious, quarantined it or delete it and corrupted its accompanying .config file. Without those pieces, the “Razer Central Service” can’t start, so Synapse throws a generic Java/JavaScript crash and never opens. Restoring the quarantined files or reinstalling Synapse fixes

    That will be the best if not even the manufacturer support can help on this
