Thanks for the report.
In regards to this bug report - It appears that if the Initial Print Temperature, Print Temperature, and Final Print Temperature aren't configured correctly (the boxes turn yellow) that it causes Small Layer Print Temperature to be in error and Cura won't slice. I don't know why it's set up that way but it makes it appear that what you have is a well hidden "expected behavior".
I got errors loading your project file. Cura will only load the model. Looking in your file I recognize that something is wrong with your your setup files. E.g. it seems to miss your quality profiles and your material profile seems to be as well not complete. You should ask your printer manufacturer for working printer definitions.
Meanwhile you can try to set the Small layer printing temperature to the normal print temperature from the involved material profile. Check your printer profile in case you want to know how the calculation for this entry is defined. The entry is called "cool_min_temperature". You will find it in the printer definition file.
