How to start .exe file with Github self-hosted runner - powershell

Question

I'm new to Github Actions and currently trying to make a CD pipeline for my web application that I run on a windows server as an executable.
In order to do so I created a self-hosted github runner with a YAML file that does the following steps on push:
Checkout repo
steps:
- name: Checkout
run: |
cd C:\Users\Administrator\source\repos\FtbMultiTask
git pull origin master
Kill running process
- name: Stop and build with dotnet
run: |
taskkill /fi "IMAGENAME eq Refresh.exe"
Publish to Folder with specific publish profile
- name: dotnet publish
run: |
taskkill /fi "IMAGENAME eq Refresh.exe"
dotnet publish C:\Users\Administrator\source\repos\FtbMultiTask\Refresh\FtbMultiTask.csproj -c Release --output "C:\Users\Administrator\Desktop\PublishProjects\FTB_MPA" -p:PublishProfile=FolderProfile
Start .exe file to actually start the app
- name: Start
run: |
start C:\Users\Administrator\Desktop\PublishProjects\FTB_MPA\Refresh.exe
It's the 4th step where things go wrong. The exe does start (it seems like it) but then immediately closes.
I tried different options of start command and even put a start Cmd.exe in front of it to see if it behaves in the same manner with Cmd.exe, and the answer is yes - it closes it immediately.
I Also tried waiting like this:
- name: Start
run: |
start Cmd.exe /wait
start C:\Users\Administrator\Desktop\PublishProjects\FTB_MPA\Refresh.exe
and like this:
- name: Start
run: |
cd C:\Users\Administrator\Desktop\PublishProjects\FTB_MPA
start Refresh.exe
I'm unable either to fix it or even detect the problem. Github produces the following output:
Run cd C:\Users\Administrator\Desktop\PublishProjects\FTB_MPA
2 cd C:\Users\Administrator\Desktop\PublishProjects\FTB_MPA
3 start Refresh.exe
4 shell: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.EXE -command ". '{0}'"
5 env:
6 DOTNET_ROOT: C:\Program Files\dotnet
