Hi,
I am using Corona 6 HF 2 to investigate your scene. Your scene does crash when I open it directly. Which only suggests to me that there are unwanted garbage dummies, missing plugin data, or anything else which is causing the crash.
A simple fix was to merge your file into a new fresh 3ds Max Scene file. Then your file did not crash anymore but I did see that your objects have two materials assigned in each. Corona MTL + Physical material. As a general good workflow, 1 object should have 1 material unless you are using multi sub-object to define multiple materials on the same object. But that was not the case in your scene. You can see this in the investigation video too I am attaching below. Please go through the video to see the fix.

Also please use the updated Corona version which is Corona 6 hotfix 2. You can download it from the website. There is a high chance of if there was any bug that existed in Corona 5 was already resolved in the updated version.
I hope this helps.

Avi
Thank you very much for your investigation... :)
i just update to corona 6 hotfix2 but still crash and then i back to corona 5
that scene just for test, i create freshly from blank scene 3dsmax.. i just added camera and light
