Please find below the link of the log.

thank you.

I took a look into the log file you've linked at Google drive.

The log contains a few thousand log entries of your Macintosh Computer:
First log entry: 27 Mar 2019 15:54:26
Last log entry: 28 Oct 2019 07:41:47

Just a small question: About which error you're talking about?
At the last day it seems you've tried something to achieve with regular expression - did you've meant that whith your question?
