/**
* There are two reasons for this issue:
* 1.LVGL API is being used across threads, such as modifying widget properties in another thread
* or within an interrupt handler during the main thread rendering process.
* 2.User-customized widget modify widget properties/styles again within the DRAW event.
*
* Therefore, ensure that LVGL is used in a single-threaded manner, or refer to
* documentation: https://docs.lvgl.io/master/porting/os.html for proper locking mechanisms.
* Additionally, ensure that only drawing-related tasks are performed within the DRAW event,
* and move widget property/style modifications to other events.
