For what reasons can it write that the file is not available when filling out the form?

Question

Google Sheets

Good afternoon.
I have one form from which data is written to a Google spreadsheet. And recently, when opening the form, it says that "The file is not available. An error occurred while working with the file. Try refreshing the page."
Refreshing the page doesn't change anything.
This inscription does not always appear. It may appear if I log in from a mobile, but from a computer, this error does not give out. etc.
And probably the strangest thing is that the data from the form is still written to the file, knocking down users with this inscription.
Guys, who realties faced this? Can you suggest how it is treated?
