apt-cache madison globalprotect
sudo apt install globalprotect=<VERSION_BEFORE_6.0.0>
sudo apt-mark hold globalprotect

Downgrade risk
Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
After downgrade
Restart the service, and keep the package held until a fixed release ships.
