Tainted nextdns logs every 30 seconds

[cowboy]

I checked the other tainted threads here. They are mostly about dcd and they were resolved with the update in 2023.
On my AC86U Router i have disabled Trend Micro (AiProtection), but still i get every 30 seconds the following log nextdns Tainted:

I have formatted my USB and installed nextdns and skynet again. But the error messages are still there.
NextDns is updated to the latest version on my AC86U Router.

On my AX86U Router where nextdns and skynet is also installed I don't get those logs.

Any solutions to this ?

This is nextdns crashing. You will have to contact them for support.

Unfortunately, there has been no response since I posted my question on the NextDNS Forum. I suspected the issue might be due to a faulty USB device, so I purchased a new one. I formatted it to ext4 using the fd command from amtm script.
But the moment i installed nextdns cli using the command

sh -c "$(curl -sL https://nextdns.io/install)"

, I experience the same logs with the kernel errors again:

NextDNS is working normally.

Nextdns can also be used with ctrld program, by ControlD. You may want to check if that works better for you:

NextDNS Mode

@cowboy have you considered other dns proxies?
