GRBL resets when limit switch is triggered while running a file from the SD card

Sure! Here's the updated version with the additional information:

Title: GRBL resets when limit switch is triggered while running a file from the SD card

Description:
I'm experiencing an issue where, when I run a file from the SD card, GRBL resets if any of the limit switches are triggered. However, when I run the same file using a Windows software (e.g., Universal Gcode Sender), if a limit switch is triggered, GRBL correctly gives a "hard limit" error instead of resetting.

This inconsistency only occurs when running from the SD card. I'm using GRBL 1.3 on an ESP32. Could anyone advise on what might be causing this behavior?
