MCD / MCD-5710

I just played MCD for the first time in a while, and I was about to go back to my old saves to see what I had done. I had previously transferred the entire game (executable and all) from a different PC to my current computer. However, when I launched MCD from the Minecraft Launcher, the game started normally, (had to re-login to the Microsoft account when I tried to boot it the first time though, and it did not need that the last time I played, which was about 6 months ago), however, once it had loaded, it had voiceover enabled by default (which has never happened any other times I installed this game), and when the log in window popped up, it was blank with nothing except the "x" button at the top right which closed the window. When I closed the window, it remained on the loading screen for quite a while (left it running for 15 mins just to be sure, and it was still loading). I don't quite know what's going on, as even when I repaired MCD and flat-out uninstalled it with all the save data, it still didn't work. I checked in my local save data to see if something was there that didn't get uninstalled, and for some reason, even though I specified to delete all the save data with the game file, the save data was still there. I would appreciate if I could find a solution to this problem soon, thank you in advance!
