Does BugSplat trap the crash ?
If so, you can read the logs while they are in the Temp folder before you send them to Trimble.
(They’ll get erased after you send them.)
If not, have you tried to see if Windows Error Reporting logged the crash ?
Check these paths …
"C:\ProgramData\Microsoft\Windows\WER\ReportArchive"
"C:\ProgramData\Microsoft\Windows\WER\ReportQueue"
Any crash reports for SketchUp will have "SketchUp.exe" in the folder name. (These are compressed folders, by the way.)
You most likely have to login to an Admin account in order to open these folders.
… or look up the error information the the Windows Event Viewer. (You’ll find it under Windows Administrative Tools if they are installed.)
