Error Loading File: Not a diagram file (error on line 4269 at column 1: Premature end of data in tag mxCell line 4267)

Dear All
Unfortunately I'm no longer able to open an important diagram I created with Draw.io.
I use the desktop version draw.io-27.0.9 to create the file.
I've tried just now also to open the file with the web version, but get the exact same error.
Many Thanks to anyone who can help,

Hello, I just had the same error. My file was saved in a iCloud-synced folder on my Mac (I saw on another subject that it can matters ?)

I can't open anymore my file.

I'am also open to any help !
Thank you 🙏

Nevermind, it worked with this solution jgraph/drawio#4358 (comment) !
Maybe @Giovanni-1-2-3 check this solution if your file is also in a folder that is cloud-synced !
