@Totovaalaplage - well you shouldnt be getting that obviously. I'm about to go away on holiday for 2 weeks, but I'm really keen to sort this out as its clearly a problem that needs resolving. From what I can see in the error messages - it looks like there is some sort of a corrupted file or folder under your VAM\Custom\Atom\Person folder. BrowserAssist ought to handle it more gracefully, so I need to fix that - but you could check whether there is anything obvious under that folder structure that looks odd or unusual. If your keen to fix it yourself, you could temporarily clear anything under that folder (by moving it somewhere else) and then restart BrowserAssist. It should then work, but you'll lose any local Person presets you have created or downloaded. You could then move the folders back one by one and hence ascertain where the problem lies. If that doesnt narrow it down or if its too complicated, then I'll pick it up with you when I get back from holiday (please remind me if I dont get in touch).
Lastly, this is probably not the best place to communicate. Maybe posing under the BrowserAssist discussion page might be better. Or if you have Discord, that's the quickest and easiest way to chat as I have my own discord channel.
