Not sure why this issue is becoming common. Issue is related to a library OB2 uses getting deleted or maybe a false positive by AV. IDK.

Check your install folder and search for Newtonsoft.Json.dll. If it doesn’t exist then try adding this with all the other DLLs.

Newtonsoft.Json.dll.zip (245.9 KB)

Make sure to unzip it ^

sadly it already exists there

Try backing up your userdata folder. It’s what holds everything important. Then try to reinstall everything

re run this command ( dotnet publish --configuration Release )
