@Jamesmor Welcome to the thread.

From what I can tell the error is being tripped when the gameguard files in active memory are scanned, that is why it is a timeable event. I watched it happen in real-time the other day by running a memory scan with PSO2 running. as soon as the scan hits the gameguard files PSO2 throws the NP1013 error. It is not that the Antivirus is even registering the files as a virus just the act of scanning the files seems to be the trigger.

@Omae-Wa-Mou-Shindeiru Try turning off avast and see if that works for you. I think we may have found the problem program but I will not be able to test it until tonight.

Some good news.

I made 4 changes and so far I have remained connected to the PSO2 for about an hour without getting the NP1013 error.

I have disabled AVG antivirus, AVG tune-up, Malewarebytes and open hardware monitor. I also put the game into window mode to see if anything was happening in the system's background well I was running the game. this combination has lead to stable gameplay for at least an hour.

Given that @CowSaysBOOM and myself both have Malwarebytes running I am thinking that might be the problem but it will have to wait until I am done work today for more testing, did this over my lunch break. if anyone else has a chance to test this let us know.

been going some digging and not gotten far with things tonight. Currently, I am upgrading Windows 10 Version 20H2 but that will not be finished for a few hours yet. based on what I have seen online it has something to do with an overlay on the game. I have disabled overlays on all of the software I typically run including Steam, Discord, and Nvidia, but still no luck.

EDIT: Windows fully updated and the problem persists.

@CowSaysBOOM in your initial post you mentioned that you are using Avast and Malwarebytes. I use AVG and Malwarebytes. AVG was taken over by Avast last year so I am wondering if one or both of our anti-virus and malware programs might be triggering the error. so far they seem to be something we have in common at least.

I timed it and I get exactly 10 min and then booted by the error.

Edit: If you are getting the error do not forget to register a bug report so that they will look into it. https://support.pso2.com/hc/en-us

I am also now getting this error after today's update.
