I have a problem with one of my latex files. I was writing when my laptop stopped working. I don't know why, but I had to force it to restart and when I turned it on I had problem with my latex file: I try to open it, but when I do Texmaker (also texstudio and texworks) don't work properly and don't open it. I tried to open it from onedrive, but all I see is a series of questions mark (like it is encrypted or something). Instead, all my other latex files have no prolem.
Can someone help me to understand what happened?
