Yep, my old nemesis: words ending in 'ER'. Of the 11 I've missed all-time, 7 have had that suffix. Just too many combos to try.
Keep in mind I use a history list, so I didn't try any previous answers. My guesses 2-6 were 'RACER', 'WAGER', 'FADER', 'MAKER', 'PAYER'. Ah well. Probably should have tried something with an 'L', but it didn't seem like there were a lot of answers with that letter left. According to WordleBot the 4 words left at the time of my final guess were 'PAYER', 'PALER', 'PAVER' and 'BALER'. Obviously I didn't get lucky.
