Hi,

I checked my installation per the link you provided, all steps were done.

1. windows version: 22H2 19045.4651

2. WSL 1 and Ubuntu 18.04 installed.

3. windows subsystem for linux option turned on.

4. After reset PC, below commands were run.

sudo apt update
sudo apt install wsl
sudo apt install dos2unix 
sudo apt install make
sudo apt install build-essential

5. try to generate the HEX file, still the same error appears.

6. open the Nios II EDS with administrator privilege, also the same error as below:
