I have the exact same issue, im using a 32gb for the Raspberry Pi , worked fine for some weeks. Then suddenly it wont boot.
I burned my fingers on de SD-Slot. When it cooled down i took it out and it was slighty bend, wit a fine crack on the top. The card is useless at the moment. Im afraid to use the 64 one in my drone .
Who has the same experience , with a faulty overheating card ?
