Please note that you are using an outdated version and a build not officially supported by OpenBoard. We had a similar bug report here #826 with the same version you're using, so I think you have the same problem.

I recommend to use the official build of OpenBoard 1.7.2 for Debian 12 instead. See Download and select the official Debian 12 package. I recommend to first uninstall OpenBoard before installing the downloaded RPM package.

Note also that the widget engine executing the applications was completely changed between 1.6.x and 1.7.x. You might have a look at the Release notes of 1.7.0 and at the Wiki page describing some aspects of the change.
