Hi @Romario Arnat,
To answer your question, you can search the navigation blade for Advanced Tools > Go and click Bash.
You can also navigate to https://<your app service name>.scm.azurewebsites.net/DebugConsole directly. This will provide the shell to navigate to cd /home/site/wwwroot/wwwroot
.
I was not able to reproduce your issue, but I would suggest reporting this error over on https://developercommunity.visualstudio.com/VisualStudio. That forum is utilized for all issues related to the Visual Studio IDE and Azure DevOps. I would also make sure you're up to date on the latest version of Visual Studio as this bug may have been mitigated already.
