When you choose Signal Tap from the Tools menu, assuming your project is already open, that's opening the existing .stp file for your project, so you are in a .stp at that point. Everything you do in Signal Tap is in a .stp file.
Go to the File menu -> New in Quartus to create a brand new .stp. See if you still have the issue there.
This all happens when Quartus is opened and then Signal Tap is opened without opening a project. Hence, there is no active *.stp file at the time of the crash. The sequence of events is:
1. Open Quartus
2. Open Signal Tap
3. Change the "Trigger Flow Control" box to State-Based
4. Crash
It also happens in the same way if a project is open with an active *.stp file. Like I said previously 20.1.1 Lite works and both 21.1 and 22.1 Lite crash.
Any ideas??
