Are there any crash logs?
Look in ~/Library/Logs/DiagnosticReports for them

Unfortunately no crash logs
This is very strange as Corona Simulator runs for me on 10.13 (with the exception of the Recent Projects list which is empty and which I am investigating). The Console log you provided didn’t show anything unusual. I wonder what’s different about our systems.
Have you tried removing the Simulator’s preferences to see if that helps?
First save them in case they contain clues to the cause of the issue by running this command in a Terminal window:
defaults read com.coronalabs.Corona\_Simulator \> ~/sim.prefs
Then delete the preferences and try to run the Simulator again:
defaults delete com.coronalabs.Corona\_Simulator
If the Simulator now runs, please PM me the saved preferences file and I’ll try to see what was causing the issue. If it doesn’t, I guess we’ll have to see if the next beta changes things.
I removed the preferences, the only thing that changed is that it asked me to login again. After that the app died as before.
Same for me after deleting preferences.
Asked me to login again and then died.
Should also add that I’m running Xcode 9 BETA 4.
Retested with Xcode 9 BETA 5 - no change, silently dies.
The way recent file lists are stored has changed in 10.13 and I had to remove the cache files to get the Recent Projects list working in my installation (apparently there’s a bug in the OS when it converts the old cache format to the new). Since this is the only issue I’ve seen so far I’m going to suggest you do the same and see if this is all related somehow.
To remove the Recent Files cache for the Corona Simulator run this command in a Terminal window (best to copy and paste it):
rm -v ~/Library/Application\ Support/com.apple.sharedfilelist/com.apple.LSSharedFileList.ApplicationRecentDocuments/com.coronalabs.corona\_simulator.sfl\*
The star at the end is correct, there maybe old and new versions of the cache file. Let me know what it prints in the Terminal window when you run it. Then restart macOS 10.13 (to clear the in-memory cache) and try to run the Simulator again.
Hi,
This got printed:
/Users/scottwilson-billing/Library/Application Support/com.apple.sharedfilelist/com.apple.LSSharedFileList.ApplicationRecentDocuments/com.coronalabs.corona_simulator.sfl
I then restarted.
Sadly it still dies immediately after launch 
Thanks for the suggestion though
It failed, apparently there are no cached files for me
Just upgraded to Beta 7 (17A352a), same issue
Can you try Daily Build 2017.3126? It’s a longshot but the fix to Recent Projects in the Welcome window is in the right area.
Hi,
Still crashes for me with the latest build.
Cheers
Scott
Same here
Just to 100% clear, we’re talking about running on new builds of macOS 10.13 beta, right? A couple of the previous posts talk about Xcode 9 betas.
Or are we talking about combinations of macOS 10.13 and Xcode 9 betas?
I’m on 10.13 Beta 8 (17A358a) but haven’t upgraded Xcode to 9 yet, so still on 8.3.3. Do you want me to try with an upgrade to Xcode?
No need.
Thanks to sterling help from @meyumeapps we’ve located the cause of the issue which seems to be something to do with the macOS color chooser. If you have a custom color picker pane installed you might want to try moving it out of ~/Library/ColorPickers to see if that makes a difference.
Yep, that did the trick! Thanks guys, not gonna ask how this relates, just happy I can code again 
It’s likely that any software that tried to display a color chooser would have had the same issue.
Which custom color picker did you have installed?
Ah, I had one from when I installed Zepplin
