Hello, I have the following issue :

If you read this then NanoPlot 1.40.0 has crashed :-(
Please try updating NanoPlot and see if that helps...

If not, please report this issue at https://github.com/wdecoster/NanoPlot/issues
If you could include the log file that would be really helpful.
Thanks!

I've seen the issue #296 but it's not a problem of chmod from kaleido for me.

Do you have an idea why I have this issue ? Thanks
