Please try the following steps:
1) close VS, delete .vs hidden folder under the solution folder, bin and obj folder
2) delete all caches under C:\Users\xxx\AppData\Local\Microsoft\VisualStudio\15.0_xxxx\ComponentModelCache
3) Try to reset vs settings by Tools-->Import and Export settings-->Reset All settings--> General.
And if your VS has any other extensions, pleaese disable them under Tools-->Extensions and Updates
After that, check Enable Javascript debuggigg for Asp.Net(Chrome,Edge and IE) option
4) enable all options under Tools-->Options-->Debugging-->Just-In-Time
5) try to clean Chrome caches and then test again.
If it still does not help, please try to reset settings in Chrome.
Besides, you could try to restart your PC.
