I don't have the hardware for testing this. Can you bisect to find the problematic commit ? I suspect that it comes from #14339 where the lvgl thread is started from a dedicated function:

https://github.com/RIOT-OS/RIOT/blob/9c749bc21406b8e2d9f4ca5633fa2169e57251ec/pkg/lvgl/contrib/lvgl.c#L161-L166

This function must be called from the main function of an application:

https://github.com/RIOT-OS/RIOT/blob/9c749bc21406b8e2d9f4ca5633fa2169e57251ec/tests/pkg_lvgl/main.c#L124

The lvgl thread creation was cutted out from `lvgl_init` because this function is now called from auto_init:

https://github.com/RIOT-OS/RIOT/blob/9c749bc21406b8e2d9f4ca5633fa2169e57251ec/sys/auto_init/screen/auto_init_lvgl.c#L46-L64

So before main is called.

It works perfectly on ARM, I don't know why this doesn't work ESP.
