Error when editing segmentations

Problem report for Slicer 4.11.0-2020-03-15 win-amd64: [please describe expected and actual behavior]

This error has happened several times in the last week. I have tried downloading the new preview versions of Slicer, but I am still getting this error. First, I can no longer read in a .nrrd file as a Volume Sequence, only a Volume. The preview options for editing the segment (grow from seeds,etc.) are no longer available. After I read in a .nrrd file, I went to Segmentations>Create New Segment>Edit Selected. Each time there is an error, I am either using the Scissors tool or the Islands tool to remove sections of the scan I do not need. The program starts to work, then puts out this error. If I accept the error and continue, it will not allow me to save any of the work done. Once I close the program, a second window pops up with several phrases like “vtkDebugLeaks has detected LEAKS!” I have a screenshot of both errors.

This message means you have run out of memory. Maybe you are working on particularly large data?
You can either add memory to your computer or downsample the data.

You need to install Sequences extension to be able to load a volume sequence.

This means that you have ran out of memory.

You either have to load less data at a time, decrease their size by cropping and/or resampling (using Crop volume module), or increase virtual memory size in your system settings (e.g., try setting it to 50GB; but this may slow down the application significantly if you load a lot of data).
