Facing issues with Blazor webapp deployed on Netlify

Hi ! Thank you. Sure, here is my repo: https://github.com/Chefty/Portfolio.
I think the indentation should be ok with my files ? I followed this thread to be sure.
I checked if the files were there by doing a right click on my webpage then, inspect element, in the sources tab. I can see the index and other folders but no _headers or _redirects files.
About Netlify continuous deployment due to the fact my website is not static I can’t use it. It needs to build to re-update everything. I use Github workflows action, you can check it out in my repo in .github/workflows/dotnetcore.yml. I hope you can find what I am doing wrong there…
