Running bash script with login session from batch file doesn't execute .bashrc

I have a batch file that is an entry point for starting a python program in wsl (since it has to use .so shared library file).

In short

The problem is that the line bash.exe --login ./start_program.sh doesn't call the .bashrc file.

In more detail:

I use WSL2 and Ubuntu18.04 from the windows store.

As I am using conda as a python environment and added the line "export DISPLAY=localhost:0.0" to the .bashrc file to let python show some data, I need the the .bashrc file to be executed before starting the python program.

I changed the ~/.profile script to contain the lines

if [-f "$HOME/.bashrc" ]; then      echo $pwd      echo $HOME      . "$HOME/.bashr"  fi  

When I start wsl manually, the .bashrc file is executed and everything is fine and when I run the script start_program.sh the program starts. The output at at the start of wsl was as expected:

<empty line>  /home/dries  

The problems start when I try to run it from a batch file. When I try either of the two

wsl.exe ./start_program.sh  bash.exe ./start_program.sh  

It doesn't call the .profile file and it fails. When the .bat file contains

bash.exe --login ./start_program.sh  

It executes the ~/.profile script, but this doesn't call the .bashrc script. The output of the .profile file is the same (empty line and /home/dries), but the .bashrc file is not called.

I suspect that it has something to do with looking for the files in windows-style or in Unix-style, but I'm not sure.

I hope someone can help me with this issue!
