Process with an id xxxx is not running.

While trying to run the solution in visual studio 2019, it gives error 'Process with an id xxxx is not running.'

it is not a code error but a windows one, please follow these steps:

1. close Visual Studio
2. open the folder in which your solution is
3. remove the .vs folder (it may be hidden)
4. restart Visual Studio
5. hit F5 to start IIS Express and debug your application

I am having this lately. Not sure what triggered it but none of the web projects are running. I deleted the .vs folder from the root.
I restart visual studio and I started my laptop. My console project are the only ones that runs.

I found a resolution for this issue. The Bitness setting in the Web tab under project properties somehow got set to Default instead of x86. For some reason, it has to be x86 for all ASP.NET projects I work on. God knows why. Can't recall messing with it. Again so misleading. Took me to days to figure this out. Hopefully this help someone.
