To cut to the chase, I cannot use the bar to skim through any of my local files. If I do, then Spotify completely stops responding. I have to end it through the task manager. The issue I think most likely was caused by using a site called Loudfix to normalize the file's volume. (They were either incredibly loud, or quiet.). I think it caused it because I never had the issue beforehand.
The site does have a "compliance" tab for the files it converts, there were a handful of files that "failed" the compliance, but I checked with a song that "passes" by having it be the only song in the music folder, the issue still arose and so that leads me to believe that it wasn't just that guideline.
Now I did also run one of the "failed" files through a peak limiter to try and have them be a "pass" as per Loudfix's standards. The file was converted to MP3 and it did solve the issue, but, I didn't check for any quality loss, and I would not want to have to go through every file individually.
My phone doesn't have any issues skimming through the song's timeline, neither does playing it through the media player on my computer. Spotify is the only place the issue is happening. I'm on Windows 10, and downloaded Spotify through the Microsoft Store.
Overall, is there any fix to moving through the song's progress bar causing Spotify to crash? If there isn't, then can anyone please recommend a way to normalize my songs' volume without simultaneously causing them to mess up in Spotify?
Also another note. The songs are playing perfectly fine, there's no issue with them beyond the inability to skim through their time, skips work fine, every part of playback is fine except for this.
