|Are you opening the browsers from shortcuts, or directly?|
If you are using shortcuts, there is a chance that something has corrupted them. I would try opening them directly, they can be found in the program files. your other choice would be by windows R to open then run window, and then typing chrome.exe. This should open directly.
If this process fails, I would advise (probably either way) restarting in safe mode with networking and downloading malwarebytes, and running. Post back the log if it finds anything.
