[CRASH/LOAD] -We can't open a shared document since v27.2.12
Hello all, I'm in trouble with a XD cloud document.
Our team (contains 10 persons) share the cloud document. The document has 10 co-editing members, links to other local documents and provides many assets.
In 26th of Feb, We founded that we all the members couldn't open the document.
When we tried to open the file, XD showed a dialog like this:
I remembered that our XD had updated automatically ( to v27.2.12 ).
Then I tried to downgrade XD ( to v27.1.12 ) and open it. It successed.
Now, v28 is live. I update XD to v28.1.12. I try to open the document again. But I can't do it. The dialog message has updated like this: 
We still can't open the file.
I contact members "Who editing the file?". But no one's editing the document.
Now, the XD old version that can open the file (v27.1.12) isn't accessible. We're completely locked out from the cloud document right now.
Please help us, if you have any ideas.
Thanks.
