For bug report of VS IDE, try report by "Help" ->"Send Feedback" within VS2019 so the IDE team can see.
Hi @18262301,
Welcome to Microsoft Q&A!
What is your project type? And please try to create a new project to check if the situation occurs in specific project?
In addition, you can update your Visual Studio to the latest version and delete the hidden .vs, bin and obj folders in the project folder.
Then, repair your VS in VS installer > More > Repair and try again.
Sincerely,
Anna
