エラー発生、ファイルが空っぽに書き換えられた

3.3の最新版にアップデートして いつも使うファイルを開くと、エラー発生と言われた。
3.2に戻って同じファイルを開くと、何もなかった。

最後的にWebブラウザにてCloudにログインして バージョン復元をしました。

We do not speak Japanese, sorry. Your message, translated with Google Translate, is quoted below. Please consider using English for better understanding.

I updated to the latest version of 3.3, and when I tried to open a file I use regularly, I was told that an error had occurred.
When I went back to 3.2 and tried to open the same file, nothing happened.

Finally, I logged into the cloud using a web browser and restored the version.

I don’t understand what is the issue and if there is any issue at all. Do you have some reproducible scenario that fails right now?
