I don't know sorry you'll need to wait for more knowledgeable people to answer xxx I was giving you my answer only after watching queens gambit xxx

Adjournments have fallen out of use since the introduction of electronic clocks capable of adding increments. Because the clocks can be preset to add an increment per move and/or a sudden death additional time allotment, play can be finished in one sitting. I'm not a fan of faster time controls, but this makes sense to me.

in addition to obvious thing of clocks it also tournament schedule issue. If of day 1 has several adjournments it would delay round 2 on next day. Would add to cost of running and attending tournaments. Also when adjournements were in use to keep schedule it sometimes necessary for chief arbiter to do a ruling on result of the game. Best my recollection arbiter could rule game as draw due to insufficient losing chances.

It was not abolished, technically. In theory, the option still exists and the rules define when is it possible to adjourn a game and how to proceed. It is just not used in practice any more.

In the old days, adjournment schedules varied. There could be a short two hour break when players eat dinner hastily while analysing the position. More commonly, it was the next day and players and their team spent the whole night analysing. Or, there would be a rest day when all adjournments were played off.
Complicated, but the main reason they've disappeared is engines that will instantly tell you the best continuation. I guess engine availability favours the weaker side who'll find resources that were not obvious to humans.
One consequence is a higher level of endgame knowledge. Previously, you could just look them up in a book whereas now they have to be played out, often with little time on the clock.

There is a full 3 hour documentary on youtube about the 1990 WC match between the champion kasparov and the challenger karpov. (The link: https://youtu.be/Rxy1wYFN29M?si=GdBxOSsI1KBwaYdh ) I think it was in game 18 (back then the championship was 24 games long) and after 5 hours of play they adjourned the game, and karpov made his move and kasparov resigned.

But the 2021 WCC game 6 was the longest world championship game ever in history, at 136 moves long and 8 1/2 hours of play, if adjournment sill existed, that possibly wouldnt have happened.
