im currently installing ffmpeg right now but still wondering if I can fix this video file.

I would check if it works with vlc. You can try to fix it with ffmpeg. This will allow you to re-code the file. Typically I take a file that's a problem and try to recode it into some other format therefore avoiding any possible direct transfer of the same errors. Seeing as most of these errors are time errors, it may work and not corrupt the video and any possible audio streams sequencing; however it may result in cutting some of the video out.

Another tact is to use ffmpeg to take only specific chunks. You can tell it to start at an offset, or only proceed a certain distance along, or both of those properties. The result is that you may end up making 2 or more partial clips and then be able to recombine them if it makes sense.

Vlc will also try to repair the video. I've done that and it can take a long time, depending on the length of the video. I've not then tried to resave it. Vlc is mostly for playing videos, and it will repair it for it's own play instance; again not sure if once it's done that if it will allow you to save that result. I've usually just used ffmpeg to try and convert, clip, or fix a video.
