I have a MVC web application for about 7 years in operation. About a month ago I've finished and deployed new version with major layout changes based on Bootstrap 5 template. Yesterday I've published minor updates - the app is running at the production server. Today, needing to make some other updates I'm not able to make the app running at my development PC anymore. The browser started loading the page, the title is set, but the page loading is not finished. I have tried to step through the layout.cshtml file - went it through completely.
Here is the last part of output of the Debug:

I've tried to change the web browser - MS Edge and Chrome, tried Debug and Release configuration. Still the same result.
When started Without Debugging (Ctrl+F5), page loaded properly.
EDIT Browser Console is empty. The page is loaded partially, because the loading indicator element is displayed.
EDIT 2 Looking at the Browser dev tools Network tab I see there are 2 fonts pending for load
I had the same problem, it was solved by disabling the "Script Debugging" option in the Run button detail.
