In the file src/XF/Install/Upgrade/2000010-200a.php you will find this line:

$permissionCache = @unserialize($admin['permission_cache']);

I believe all that's required is to change it to:

$permissionCache = @unserialize($admin['permission_cache']) ?: [];

And then hit refresh and the process should continue.
