Clicking Print button on License Agreement Dialog lock installation process - WiX 6.0.2

Question

After upgrading our Installer project from WiX 5.0.2 to WiX 6.0.2 the Print button on License Agreement Dialog no longer works.
Our installation process is a bootstrapper exe that starts an external MSI installation.
When I click the Print button on the MSI License Agreement Dialog, I get an error message stating the setup failed (see below).

This error dialog is unresponsive and I'm unable to open the log file link.
It looks like installation process is completely locked up and the only way to close the dialog is to end the task within Task Manager.

Oddly though, If I run the MSI directly the Print button works as expected, so this only appears to be and issue when running the MSI from the Bootstrap exe.

Is this a known issue with WiX 6.0.2?
I know we have had issues with the Print button in the past when moving from WiX 3.x to WiX 4 & 5.

I'm fuzzy on exactly what you're doing, but I've never heard of anything like that. The log file in the %TMP% folder might give you some clues. Also, attaching a debugger and checking whether you're getting an exception would probably be enlightening.
