Cannot Access being used by another process

• Version: 13.5.1.0

• Target: .Net Core 5.0 & Node 15.10.0

• Problem: I have created an empty ASP.Net project. Performed all steps as described to install Electron.NET and include it in the project. Now when I enter "electronize start" I get this error:

• Error:

Steps to Reproduce:
Follow the install instruction.

I created a new .NET 5 project and followed the setup steps. There's no problem.

Try deleting the obj\Host-folder and try again. If necessary, try a project again in a different directory?

I get the same, .net 8 project. It runs once but after that the files remain locked and I cannot rebuild or rerun the application.
Cant remove the files either

$ rm -rf obj/
rm: cannot remove 'obj/Host/bin': Device or resource busy
rm: cannot remove 'obj/Host/node_modules/.bin': Device or resource busy
rm: cannot remove 'obj/Host/node_modules/electron/dist/icudtl.dat': Device or resource busy
