Microsoft Visual Studio 2010 Package doesnt load correctly

I am trying to open a project that I have been working on for a while now. Everything was going well. and then I had to download FileZilla for ftp works. That instance somehow switched my default browser from MS Edge to Opera which was downloaded with FileZilla. So when I ran my VS2010 project it initially ran on Opera. I deleted the Opera and tried to use Edge like before.But my solution folder doesn't seem to load and neither does my project run without crashing .I have tried to uninstall and re-install when I do that I get these errors

PACKAGE DID NOT LOAD CORRECTLY

PACAGE DID NOT LOAD CORRECTLY

SAME AS PREVIOUS

SAME AS PREVIOUS

similarly. My solution folder doesn't load anything which contains all the packages

When I FORCE run my project it runs and then the IDE doesn't respond for a while and then it says "Unable to start the program (file path) There are no more files"
