23.1 std MegaWizard disappear

Question

I instatiate an ALTPLL. At the very beginning, I can set all the parameters, Output clocks. But later When I want to change some parameters, I can lanuch ALTPLL MegaWizard Plug-In Manager, when I go the the 3rd step(Output Clocks), it froze and disappeared in several mininutes. I try many times, the same happens. But If I use an earlier version 18.1.0625 std, everything is OK. So can anyone tell me why this happends in 23.1std and how to fix it? Thanks.

Hi,it's a known bug, search forum for "23.1 pll".According to Intel employe statement in one of the thread, a patch for 23.1 std has been released, but I didn't yet see it. Previous threads suggest to use 22.1 to generate PLL, also copying related Quartus files to 23.1 installation was reported as an (inofficial) solution.I wasn't yet able to locate the bug in known Quartus issues, not sure if it's my fault.
