Microsoft Access was unable to save the form or report because it displays characters from a language that cannot be saved in the current system locale. Switch your system locale to the language of the form or report, and then try again.
Check your Windows language settings in Settings > Time & Language > Language & Region.
Do the same thing for Office language settings in File > Options > Language.

I suspect there's an error in Windows. Could you please recommend a free program that can maintain Windows or fix errors that might be related to my problem?
Can you open Access itself?
If no, then do an Office repair or a complete reinstallation
If yes, then your database may be corrupted.
Try first compacting your database externally and then decompiling your database using command line switches.
