Does an uncounseled guilty plea constitute a structural error that can be raised at any time?

QUESTION(S) PRESENTED | L. Does an uncounseled guilty plea -where defense counsel was suspended and thus : “ineligible to practice in federal court" at that time -constitute a "structural error" which can be | raised at any time because the resulting conviction is void? I. Did the Southern District of Texas show actual or apparent judicial bias when during Petitioner's Rule 11 plea colloquy he explicitly stated he did NOT understand his rights under FRCrimP 11(b)(1)(C.E) -and the district judge simply ignored his response and entered his now unknowing guilty plea? ii
