Crash on Import: IndexOutOfRangeException when processing Aircurve 10 VAuto data

[piegunn]

When attempting to import data from my ResMed SD card, the application crashes. The error seems to occur during the processing of a specific night's data, not during the initial file discovery

Steps to Reproduce

• Launch the CPAP Exporter application.
• Navigate to the data import screen.
• Select the folder containing the complete data from my ResMed SD card.
• Initiate the import process.
• The application processes for about 30 seconds and then displays the error

I tried deleting certain months from the data one-by-one but it didn't seem to help and the issue doesn't seem to be with the actual importing anyway. Also tried copying the SD Card data to the main SSD drive but that didn't help, same issue.

The full SD card data is here in case that helps: https://mega.nz file/FGZxSCKC#zvyX1UaYKw5ByUKpc3wq6Fbpf-lDd-wNnTu9Q4AjzuY

The application crashes and an IndexOutOfRangeException error is generated. The import process does not complete.

Error Details (Stack Trace)
Here is the error log from the application. The crash appears to happen deep within the cpaplib library when trying to analyze the breathing signal data.

System.IndexOutOfRangeException: Index was outside the bounds of the array.
