DLight crash during show

Hi,
I´m on 4.0.26 64 bit Windows 10 and DLight keeps crashing at some point during a show for About a month now. It doesn´t always happen. Usually at the end for some reason. I´m using a custom build midi-controller for ages now with DLight.
Any ideas on why this could happen? The DLight window just disappears within a blink of the eye. I´m using a Lenovo Yoga 900S with core m7, 8gb ram and Windows 10 Home 64bit.

Hi Stebian,
There must be a reason for DL to crash. Not expected though but we should find a way to fix it.
I need to know if it crashes on some manual stuff (if it crashes when you manipulate your midi hardware... but I doubt).
Does your windows system is up to date?
Can you post your sho?

It´s hard to say when exactly it crashes. My midi hardware does sometimes wiggle between slider values. But it always did that (I´m using it for serveral years now with dLight) and the crashes just began in November past year, no matter witch 4.0.x version I used. Before I only ever made it crash by experimenting with OSC (when I accidentally send out of range values).
Windows is always up to date.
I started DLight just now and will let it run without midi hardware throughout the night. Is there a log file by any chance that could help figuring out why it crashes?

I attached a .sho.

Thanks for your help!

DLight is still up and running without midi. I´m beginning to think it might be my midi hardware that for some reason is causing DLight to crash...

maybe you have a midi loop?

What is a midi loop?
