You may use
(?s)^\S+\s+\S+\s+(?<Exception_type>.*$)
See the regex demo
The ^\S+\s+\S+\s+ matches the first 2 non-whitespace chunks of text separated with 1+ whitespaces and the rest is captured into Group 1.
To remove the GUID, you will need to use a second step:
\b[a-fA-F0-9]{8}(?:-[a-fA-F0-9]{4}){3}-[a-fA-F0-9]{12}\b
See the regex demo, replace with an empty string.
Here, \b are word boundaries and [a-fA-F0-9] matches a hex char.
