Error (12252): Border: 2020.05.20.09:07:13 Error: seq: Error during execution of "{C:/intelfpga_lite/19.1/quartus/../nios2eds/Nios II Command Shell.bat} make all 2>> stderr.txt": child process exited abnormally

Can you try out this solution?

1) https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/emif/2018/error--s0--error-during-execution-of---quartus-installation--nio.html

Or

2)

Go to check the jtagserver.exe (same path as in the generate log) whether it is enabled in the firewall for all network types, see below:

jtagserver firewall

You may have to click on the 'Change settings' button with a shield icon on it before the firewall rules are editable - they are locked against being changed by software.

You might need to have the admin to do this.

Thanks,
