Snap error in satellite image

I installed Snap. But I can only open satellite image. Does not take the necessary steps for classification and it freezes.

Please describe your problem a bit more.
What data are you using, what steps you applied, how much RAM does your machine have.

We need more information to narrow down the problem

I am using Sentinel-2A data.
Transactions action: Open Product-Open RGB Window
Unable to perform actions: resampling-save product-reproduct

My machine has RAM: 6 GB

6 GB sounds a bit uncommon (usually 4, 8 or 16…), but regardless of this it might not be enough for these data volumes. Can you display single bands?

Features are available in the screenshot. Yes, i can viewing the bands.

maybe you can create a subset of the image before you proceed to reduce the file size?

Thank you, i will try.
