Hi, while synthesising on Quartus Version 19.1.0 Build 240 03/26/2019 SJ Pro Edition for Arria 10 10AX115N2F45E1SG (Terasic de5a-net-ddr4 board) i get this internal error message which I don't understand, can someone help? Error occurring both on Linux Debian 10 and Windows 10.

Error message:

IE usually is a bug. Can you attached us the design.qar files for duplication?

Also, can you upgrade the Quartus to 20.1 (latest version)
