homebrew-cask: Error on Casking VLC

Finally found out a workaround. See below

General troubleshooting steps

• I understand that if I ignore these instructions, my issue may be closed without review.

• I have retried my command with --force.

• I ran brew update-reset && brew update and retried my command.

• I ran brew doctor, fixed as many issues as possible and retried my command.

• I have checked the instructions for reporting bugs.

• I made doubly sure this is not a checksum does not match error.

Description of issue

Getting this error when i try to cask the VLC Player, tried BlueJ for reference. That one worked, VLC does not. Hope you can help me out with that. Have this issue randomly appearing with random pakages. I know there have been already xattr bugs. I tried already some fixes. Would be happy if anybody knows how to solve that 😃 Thank you in advance!

Command that failed

brew cask install vlc
