New ContributorCyclone IV PLL IP megawizard crash
I can confirm that PLL Megawizard is crashing in Quartus 23.1 when advancing to the Output Clock tab. I tried with Cyclone IV E and Cyclone 10 LP, just using default settings. Also a PLL component defined in Quartus 19.1 reopened in 23.1 crashed when selecting output clocks.
The problem has been already reported, see e.g.

The first link however contains already a solution by copying 22.1 Megawizard files to 23.1 installation. I don't see known issues related to PLL Megawizard reported for Quartus-23.1std.0.991-windows in FPGA knowledgebase, shouldn't the problem appear there 2 month after first bug reports? At least the problem should be known internally to avoid misleading suggestions as above.
Definitely waiting for an official patch.

New ContributorThank you very much for the links to those possible solutions!!, I am already downloading version 22.1 and will confirm later if it worked
