Hi @hhhh4444 hmm MetaMask support recommends my post 
I am glad 
Contact me on Telegram 
trust me a little.
I checked 2 such files this week. One of them was a little corrupted (but it was possible to fix it)
and the second file was fine.
If you don’t trust Telegram, you can upload it to the encrypted cloud https://proton.me/drive
and I’ll tell you my opinion 
diagnostics is free hehe
