   Now when "DatePattern" is "yyyy-MM-dd", it reproduces the issue.
   
   ```
   log4net:ERROR RollingFileAppender: INTERNAL ERROR. Append is False but 
OutputFile [...\Log\2025-03-21.1.log] already exists.
   ```
   
   When "DatePattern" is 'yyyy-MM-dd".log"', it causes the following error:
   
   ```
   log4net:ERROR Could not create Appender [LogFileAppender] of type 
[log4net.Appender.RollingFileAppender]. Reported error follows.
