A similar problem has been reported here in the past. My display did it a few times too. But this problem has not been reported for a long time. Maybe also because people are buying touchscreens so they don't have to use Marlin mode :-) Are you sure you are using the latest FW for TFT?

The solution could be shielding the cabling leading to the display. see this post: https://github.com/bigtreetech/BTT-TFT35-E3-V3.0/issues/80#issuecomment-1762893295

Sorry, I added some of the adjustments suggested in the Marlin firmware and I bought some shielding. It hasn't happened again yet so one of those fixed it. Now I just need to figure out how to get idex options to show in the BTT touchscreen ui!
