The problem is probably in the Software, and probably in the FPGA code you are trying to compile. Of course, by now you've also changed the configuration of LabVIEW from "a configuration that worked with earlier FPGA code" to "an unknown configuration that so far doesn't work with any FPGA code used for compilation".
When you got the very first Error, the "ideal" thing to have done would have been to reboot, then attempt to compile the last FPGA code that succeeded. I'm guessing that if you had done this, the compilation would have worked, suggesting that the problem was in the current version of the FPGA code. I presume you have been using some form of Version Control Software (like Git, Mercurial, or Subversion) -- see if the earlier version will compile.
If not, you might need to "fix" LabVIEW, itself. Before attempting a "repair", do you have another PC with a working version of LabVIEW installed? Try compiling there.
Speaking only from my own experience (several hundred LabVIEW installs, for myself, my colleagues, and my students), I would recommend an "uninstall (all NI Software)/reinstall" sequence. This has been described many times on the Forum, so I won't do it (again).
I noticed that you did not attach the FPGA code that produced the Error Messages, so we could not "look at it" and suggest what might be wrong, and couldn't try to compile it ourselves and see what errors popped up. But you did attach blurry images of the Error Messages ...
