Hi, Jaemin
Can you follow below, also make sure you are using 64bit system.
Starting with Nios II EDS in Intel Quartus Prime Pro Edition version 19.2 and Intel Quartus Prime Standard Edition version 19.1, the Cygwin component in the Windows version of Nios II EDS has been removed and replaced with WSL. For installation instructions, refer to the Installing Windows Subsystem for Linux (WSL) on the Windows section in the Nios II Software Developer Handbook. For machines installed with McAfee Endpoint Security, the minimum requirement is Windows 10 Version 1809 (OS build 17763). If you are using a network drive for the Nios II EDS, the minimum requirement is Windows 10 Version 1903 (OS build 18362).
