Hi, pNovo has an update on June 2022 and the question should have been fixed. 
Could you download the newer version from 
http://pfind.org/software/pNovo/index.html and try the search again?

I am having a similar issue, I setup parameters in pNovo Search 3.1.3 and once I 
click Search the buttons turns grey and the program seems to freeze (result files 
remain at 0 kb and I have tried running it several times overnight and it remains 
frozen). I have recently applied for a new license, as I thought it could be time-
sensitive, but even then it still doesn't work.

运行后，pNOVO界面没有任何反应，无进度条。
新生成的2个文件夹Result和Param，之后也无反应。
