Unreadable Files (all zeroes, unrepairable)
Edit: Updates to information.
I've been getting "Cannot read file..." errors on several of my MuseScore files. I'm using a Mac on macOS Mojave (ver. 10.14.5; not the most recent update because of a software issue that prevents me from updating) and have the latest version of MuseScore (184.108.40.20671). This sort of error started to occur about three weeks ago, around the time when the computer also experienced reoccurring kernel panics (basically crashes and resets from a software issue; it may be related/causing this issue too). Attached below are two of the problematic files. I located hidden backup files for both of them and they are openable but I kept them hidden for now because I'm literally too scared to open them again. Previous similar issues that dated back a long way often have shown that these files are either empty or have all zeroes (confirmed in comments). There is also an iCloud and hard drive backup with these files that I can provide access to if needed. If you need more information, I will do my best to help. Thank you for any support!
