Hi Sir, Is this KDB will help?

https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/tools/2019/internal-error--sub-system--oct--file---quartus-periph-oct-octge0.html

​thank you, I tried versions 18.0, 18.1, 19.1 and 19.3 all crash.

Is your design have PR.If not then the the KDB might not related.

can you share more details on your design. Is the design is generated example design? or custom design using the DDR4 IP?

From the error message, its looks like there are some problem on the RZQ pin. Is your design have any special constraint to this pin? Maybe you can remove all the pin assignment (location, I/O standard, termination) of this pin and try to recompile?
