'\Program Files\dotnet\SDK\7.0.101\DotnetTools\dotnet-watch\7.0.101-servicing.22579.2\tools\net7.0\any\middleware\Microsoft.AspNetCore.Watch.BrowserRefresh.dll'

This path needs to be fully qualified. It needs to start with drive letter.

Thanks for response. It could be a configuration of VS, but I don't know how/where to fix it.

I workaround the issue by modify the folder name.

C:\Program Files\dotnet\sdk\7.0.201\DotnetTools\dotnet-watch -> C:\Program Files\dotnet\sdk\7.0.201\DotnetTools\dotnet-watch2
