Logging is in progress writing data to: C:\WINDOWS\TEMP\scoped_dir26992_1680087207 That data will be stitched into a single file (this one) once logging has stopped. If logging was interrupted, you can stitch a NetLog file out of the .inprogress directory manually using: https://chromium.googlesource.com/chromium/src/+/main/net/tools/stitch_net_log_files.py
