Just finished the last mission halo on legendary in 14 minutes 13 seconds, meaning that for legendary I have a combined solo time for all missions of around 2 and a half hours which meets the devastating achievement criteria of under 3 hours, yet I’ve not received any achievement in career or on steam. This happened on Wednesday as well for the laso a preference for pain achievement, although this one showed as being unlocked in career but not on steam. During this time I’ve still been able to unlock all the par score achievements and the missions/multiplayer and medals total achievements so my steam is still unlocking other achievements fine, it’s just these two that won’t unlock
I don’t have a solution but wanted to piggyback on your post because I’m having trouble too.
I’m not playing on Steam, but Achievements are also not unlocking on Xbox Gamepass PC. I played through the “Floodgate” mission on Halo 3 earlier today and not only does the game not recognize I completed the level but no Xbox Live Achievement unlocked either.
Are any of your achievements unlocking or is it just certain ones? Because I had a problem a few weeks ago where nothing would unlock and turns out my spybot anti beacon was blocking microsoft from communicating with steam on my pc so none of the achievements were being registered
Not sure if this is the same for xbox gamepass on pc but this video fixed that problem for me Halo MMC PC No Achievements fix! - YouTube
Also had the LASO not unlock on Steam but did in Xbox game bar

Exact same situation. I have credit on my xbox live account but not Steam.
Seems to be a glitch with the triggers. My Devastating randomly popped in a multiplayer lobby.
