Check all output paths, including those for render elements, are correctly set to existing directories. Misconfigured paths can lead to errors.
Check if the file paths and names contain only English characters, as non-English characters can cause input/output errors.
If saving files to a network drive, check that you have the necessary write permissions and that the network connection is stable.
Some of such errors are from known 3ds Max bugs that add non-existent paths to render elements. check your render elements and delete or correct any invalid output paths using the Asset Tracker (Shift+T).
