The shotcut closes when I use lut

I’m using a 3dl file or a cube and the program is closing. Why is this happening? It can be fixed?

Can you give the link of the LUTs ?
The best would be to grab a log…

you can locate your shotcut-log.txt file in AppData (see other question below for more information) and paste it into a bug report.

I do not know. It works for me with v18.05 on Windows and the few LUTs I have. If you cannot share your LUT here, you can upload it more privately here, and I will test it.
