Nios II Eclipse report error when run the mem_init_generate command

i am working on a project with a Nios II inside C4 FPGA, which uses on chip memory as the RAM.

so after i build the project, i still need to run make targets-->Build -->mem_init_generate to generate the initialzation HEX file for the on chip RAM.

this works well so far.

but yesterday i must renew my laptop per the requirement from the company, and then i need to re-install the same tool chain: Quartus 21.1, WSL 18.04 on windows, CDT 8.8.1.

i believe i have done all steps per instructions, and the project can be built without error. but when i try to generate the HEX file, it reported below error.(I copied all information in the console window in case it helps)

please help me on this, thank you.
