This is caused by a conflict in the default simulation pins file (Marlin/src/pins/native/pins_RAMPS_NATIVE.h),

#define EXP2_08_PIN                           41  // KILL
...
#if ANY(TFT_COLOR_UI, TFT_CLASSIC_UI, TFT_LVGL_UI)
...
  #define SD_DETECT_PIN                       41
...
#ifndef KILL_PIN
  #define KILL_PIN                   EXP2_08_PIN
#endif

If you set #define KILL_PIN 11 there is no conflict, and it still fails to work.

Under linux something very odd is going on.
If you click on SD Card present then it stops taking gcodes

On the topic of SD card issues in the Sim...

I found that I cannot copy TFT_LVGL_UI assets to fs.img because it's too small. Assets are ~5MB and the image is 100MB, so that doesn't add up:

@ellensp I can't reproduce that, once I set the KILL_PIN to resolve the conflict the sd card woks as expected on linux, when there is still a conflict clicking SD Card Present will cause Marlin to stop responding as it triggers kill.

@thisiskeithb at least for me my OS (Linux Mint) mounts the image as read only unless I manually mount it writable from the command line, which can make some utilities report not enough space rather than correctly reporting read only.

Seems to have been a corrupted sdcard image
