avast-security can no longer be installed via homebrew-cask?

General troubleshooting steps

[x] I understand that if I ignore these instructions, my issue may be closed without review.
[x] I have retried my command with --force.
[x] I ran brew update-reset && brew update and retried my command.
[x] I ran brew doctor, fixed as many issues as possible and retried my command.
[x] I have checked the instructions for reporting bugs.
[x] I made doubly sure this is not a checksum does not match error.

Description of issue

I updated homebrew using 'brew update' and saw that I had an update to avast-security, which I had previously installed. I attempted to update the cask. I use the buo/homebrew-cask-upgrade tap (https://github.com/buo/homebrew-cask-upgrade) to make it easier for me when upgrading (if that makes a difference, but I figure not since manual install doesn't work anyway)

Attempting to use the commands from that tap (brew cu -a), homebrew first uninstalled the old version then install the new one. That's where I encounter the same issue no matter what I attempt, even after all troubleshooting attempts

I suspect that it may have something to do with the fact that Apple depreciated kernel extensions in Big Sur so they had to change the way parts of the application is installed and functions (https://forum.avast.com/index.php?topic=240363.0)

There's a separate (but very related) issue where using --force when the app is manually installed does not work (Not sure if I need to make a separate issue for that?)

Command that failed

brew install --cask avast-security

Output of command with `--verbose --debug`

↳ brew install --cask --verbose --debug avast-security

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and which additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew-provided
script of the same name. We found the following "config" scripts:
  /Users/matthewgan/.pyenv/shims/python-config
  /Users/matthewgan/.pyenv/shims/python3-config
  /Users/matthewgan/.pyenv/shims/python3.8-config

Warning: Homebrew's sbin was not found in your PATH but you have installed
formulae that put executables in /usr/local/sbin.
Consider setting the PATH for example like so:
  echo 'export PATH="/usr/local/sbin:$PATH"' >> ~/.zshrc

Does the install succeed if you pass the --no-quarantine flag?

No. Pretty much the same output as before, minus the gatekeeper bypass and quarantine output. I tried with --force too, but still the same end result

↳ brew install --cask --verbose --debug --no-quarantine --force avast-security
