Illegal Flash App

Question: When I leave the SD card in the TFT when I power it on, I get the Illegal Flash App error and I have to flash all over again. Is there something I am doing wrong? Is there a better way to upload my projects where I do not have to remember to remove my SD card? Would something like OctoPrint work? Thanks in advance!!

Empty your SD card. It sounds like something is being interpreted as a flash fw update
