Just one thought - from past experience, these firewalls (esp 3rd party stuff) can continue to wreak all sorts of grief on you, despite you believing you’ve disabled things ok…
If you can, try to stop it from even launching up at boot-time - you’ll have to dig around for some info specific to you, for how to achieve that. I say this any time anyone mentions ‘disabling firewall’ - these apps can be so insidious and tamper with so many low-level system files/procedures, that they don’t let you simply ‘disable’ them that easily… They hate not being in control.
Under the hood, its like (to itself) "…yeah, yeah - I’ll let you think you’ve deactivated me, but, ‘sorry dave, I can’t let you do that…’ "
HTH.
You too, keep safe and well…
