Can't open my webpage project after Express Update!!!

Help! I am wrapping up an online course on Friday (everything is due by Friday) and I spent the last two days working on a Webpage in Adobe Express. This morning, I woke up to an upgrade to Adobe Express. It required that I import the original file I was working on into the new version. No success. I keep getting a window saying 'Something went wrong'. Now, my file is inaccessible. How do I recover this? I am so frustrated with this issue. I have tried all day to open my project. I now have to rebuild the entire project in Google because I don't have the time to deal with this before the deadline.
