Is there a version compatible problem or anything else?

[luc-github]

What Marlin version are you using ?

[RockONthefeel]

Marlin 2.0 Bugfix Branch based on fysetc_e4

static Sd2Card sdcard;
sdcard = card.getSd2Card();
if (!sd_volume.init(&sdcard)) {
return false;
}

may this can solve the problem?

[luc-github]

no your issue is related to Marlin version
40774af

[luc-github]

so looks like you use old version, in that case specifiy branch 2.0.7 of esp3dlib in platformio
