Unable to extract DFU tool for Wio Lite RISC-V

I am trying to extract the DFU firmware tool so I can finally use my Wio Lite RISC-V. However, when I try to open the archive using 7zip it gives the error that it cannot open the archive. I tried with winzip 25 and it was able to get further. Below is the log from my attempt to extract the tool. It appears to be corrupted. Does anybody know where I can find a non-corrupt version? TIA
