ZXPsigncmd Error - Arguments are invalid. Process failed.

Hi, i created the digital sign with zxpsigncmd (selfSign) and now i'm trying to create the zxp. I already did this once, time ago, and it works well. This time, it keep giving me this error:

Error - Arguments are invalid. Process failed.

I tried several paths and combinations, but nothing.

I used this string (all files are in c: and the script folder is in c:\smart):

zxpsigncmd -sign smart smart.zxp digitalSign.p12 myPassword -tsa http://time.certum.pl/

(i alsto tried without timestamp)

I'm using windows 11.

Edit: also tried on win 10 pro, same issue.

Any idea?

Thanks
