When I correctly install the right version of a package (to avoid the NU1605 error) this happen :
Échec du chargement de l'assembly : C:\Users\MyName\.nuget\packages\uipath.mail.activities\1.22.2\lib/net6.0-windows7.0/UiPath.Mail.Activities.dlli
It’s translate to : “Failed to load assembly”. After a bit of researche, I tried to delete the folder 1.22.2 didn’t work, delete the folder 1.22.2 then reboot didn’t work. Try to uninstall reinstall and now I can’t install it again.
