Question Legion 5 Pro - upgraded my RAM and noticed this crack ?

[Tanakan]

Hello!
I recently upgraded my RAM and I noticed some kind of "crack" on the part circled in the picture. What is that? Could I have problems with my warranty?
I was very careful in the process, I don't think I caused that.
Thank you in advance!

i looks like a torn than a crack to me, is the thing soft? if so, you shouldn't be worried.

Thank you kindly for your answer.
I noticed the tear from the picture, after I finished upgrading and closing the back panel. I wouldn't open it again because the process was very tedious. I just hope that tear wouldn't cause problems with my warranty if it will ever come to that.
I couldn't have caused that just by touching it..
