Error generating feed

Hello,

i can't generate any feed.
After examining the log, I came across this error:
Error generating feed id = 1
System.IO.IOException: Invalid argument
    at Interop.ThrowExceptionForIoErrno (ErrorInfo errorInfo, String path, Boolean isDirectory, Func`2 errorRewriter)
    at Microsoft.Win32.SafeHandles.SafeFileHandle.Open (String path, OpenFlags flags, Int32 mode)
    at System.IO.FileStream..ctor (String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options)
    at FoxNetSoft.Plugin.Feed.Manager.Core.CustomFeedClient.GenerateFeed (FeedRec feed, IList`1 & reportMessage)
    at FoxNetSoft.Plugin.Feed.Manager.Core.FeedManagerExport.ExportFeed (FeedRec feed, Boolean uploadFTP)

In debug plugin mode this is in the log::
2020.12.22 23: 41: 41: 8208 *******
FeedManagerTaskController. RunTask feedId = 1, uploadFTP = False

Can you advise me on what the problem might be?
Thank you

Download the new release and upgrade the plugin.
Overwrite new files and restart the nopcommerce instance.
