Getting "General Input/Output Error message when trying to save spreadsheet

Running Libre version 6.2.3.2, when trying to save one specific spreadsheet file I get this message: Error saving the document abc: General Error. General Input/output error…I get the same message when trying to “Save As” and rename the file.

Do not get this message when trying to close any other file

HELP!!

This looks like a bug. First try with a newer version - e.g. 6.2.8 or 6.3.3; if it doesn’t help, file a bug report and attach the file if possible.

thanks…just created a whole new file and copied everything over, then went and downloaded the newer version of LibreOffice and I can now save the file!!
