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.
It's very annoying thing, help!
