Ink file does not save properly

I am currently experiencing an issue where the ink file I am working on refuses to save any changes I make- save project appears to do nothing and if I hit the "x" button and try to save when it warns me about losing unsaved changes, it just closes that window and leaves the ink file open- the only way to close the ink file is to do so without saving changes, causing me to lose any progress. I have tried copying all the text over to a new ink file, restarting my pc, and uninstalling/reinstalling ink. nothing has worked so far.
