Sorry to hear that! Could you try running without plugins and see if that helps:

pn --safemode

If it's this, it may be that one of the plugins installed is no longer compatible with the new version and I missed it. Let me know!

Thank you for your rapid reply, but unfortunately it is the same

Interesting, it says it couldn't create a user settings directory. Is your system locked down in some way, and had you perhaps used the portable version before?

If you had portable before, you could try dropping this file in the PN directory:

https://github.com/simonsteele/pn/blob/master/pnwtl/installer/configs/portable/config.xml

this will make it use the specified directory (e.g. settings) to store settings rather than relying on your user settings directory.

Well,

I tried what you suggested, put the config file in the PN portable directory.

Found out there were some issues regarding the access to the Program Files folder.

More or less after movin the whole PN folder to the Desktop looks like it is working again.

Pitty it was working before in the Program Files (x86) and not after the upgrade / unzip portable PN files to PN folder.

Anyway thank you for help! I am back with PN !!
