When opening Studio files that are corrupt or otherwise unable to open, Studio sometimes closes out immediately if opening the file results in an error. This gets frustrating when trying to figure out what is causing the error without having to find the log file for it. It’s best when Studio gets an error, you automatically know why with the message.
Repro
This does not happen 100% exactly, but somewhere around 50-75%
Navigate to a corrupt .rbxl file (in this case, a missing header or 0 byte file)
Try to open it
If Studio gets an error, you may see it close immediately
Can you please PM me the .rbxl files you are seeing this behavior with? Also if you could please PM me the crash dump / log file as the link you provided either no longer exists or is private. These will help to investigate the bug you’re seeing.
When attempting to open these files, are you opening them from an opened place or from the template page (window after you log into Studio to select a place to open)?
