I am having the same problem and it is HIGHLY irritating. I'm on Windows 10.

These solutions DO NOT WORK:
1. Exiting and restarting the Visual Studio IDE
2. Deleting and recreating the .vcxproj and .sln files

This solution WORKS:
3. Restarting the computer

Just encountered this myself for the first time this morning. Exiting VS and re-opening fixed it for me though.

If my filename theory is correct then restarting VS might make a difference. The editor tabs could be re-opened with a different file name than before. It doesn't take long to reappear though so it's not really a solution.

Also: I've noticed that the editor tabs for 'problem' files often don't re-open when you restart VS. The IDE starts but those tabs aren't there. This also fits my filename theory - there's something "wrong" with the filenames on some of the tabs.

My tabs close altogether every time I exit / reopen since upgrading to 2017. They never save current progress anymore.

With me it's only certain files that fail to re-open. I'm sure it's all related to the same bug somewhere deep inside VS.

(And really, how hard can it be for them to log all file names to a text file and find this?)

Another day of crashing.... I'm fairly sure the tabs that crash are the ones that were opened by double-clicking an error message in the compiler output window.

IDE refuses to close, I have to use task manager.

This is NOT fixed. New report here:
