Also why can't you update, e.g. what error messages are displayed ?
Windows 10 Home 2004 64bit/ Acer Aspire F15/ Intel Core i5 7200U 2.5GHz, 8GB DDR4 memory, 256GB SSD, 1TB HDD/ avast! free 20.8.2432 (build 20.8.5684.602) UI-1.0.566/ WinPatrol+/ Firefox, uBlock Origin, uMatrix/ MailWasher Pro/ Avast! Mobile Security

That error message is usually associated with firewall blocking.

What is your operating system and  firewall ?
Does it allow avast.setup internet access ?
- If it does delete the entry for it and do a manual update, this should force the firewall to ask permission again. 

Do you get the same error when you try a manual update from the avastUI, Maintenance, Update, Update engine and virus definitions ?

Windows XP Home Edition SP3 - My Firewall cannot be accessed because of an unidentified problem.. Nope manually updating doesn't work either...

That is more than likely the underlying cause to why your updates are failing, As DavidR already asked what is your firewall?

Try running the fixit tool http://go.microsoft.com/?linkid=9662461 and see if that repairs your firewall, if that doesn't work i would be downloading a new copy of the windows firewall from microsoft and saving then delet the one you have and install the new.
Even better would be to get rid of the windows xp firewall all together as it's not good and install something like the free Online Armor or Privatefirewall but that is only if you confident with firewalls.

Well the windows XP firewall shouldn't be the issue as it has ZERO outbound checking/protection.

If you have a problem with the firewall "cannot be accessed because of an unidentified problem" it would be interesting to know why and if this might in somehow impact on avast's update function.  Hopefully the fixit resolve the problem with the firewall, but I don't know if that would resolve the update problem.

If you can try to access the XP firewall from the control panel , windows firewall and try to capture any error message in full or attach a screenshot of the error window.
