You have an unusually large log file. 7.4MB is extremely rare and definitely shows something wrong.
I am also noticing quite a few plugins, and my guess is there is a conflict somewhere between some other plugin or plugins and the TBM.
The only thing I can suggest, for now, is to remove all 3rd party plugins (simply drag them out of the plugins folder to a safe place), and then reload the TBM. Keep Gizmo in there.
If it runs normally, replace the plugins 1 at a time until a crash happens. Make sure you replace the plugins with the sim shut down.
If the TBM does not run normally with plugins removed, please post another log file.
