Is this standalone ModelSim or the version included with Quartus? What version of Quartus are you installing? Modelsim has not been included with Quartus for a while (it's Questa now) so you're probably using an old version that isn't compatible with Windows 11.

I have the version of ModelSim included with Quartus V20.1.1, the install page is here: Intel® Quartus® Prime Lite Edition Design Software Version 20.1.1 for Windows. I originally tried downloading and launching the version included with Quartus 19.1, but that software had the same issue. Although I can launch Quartus just fine. I am using ModelSim since it is the version that I need for my computer design course. I could try Questa, but I don't see any indication that there is a free version for educational purposes. If there is, I would be open to trying it and seeing if it is compatible with my projects.
