I have been having the same issue over the last few weeks. I have been dealing with it up until tonight when I reached the first trial of Shadowbringers. I can not make it through an entire attempt without the direct x crash and it takes me well over a minute or more to log back in because of a queue. This means that making the DPS check is that much harder and we end up wiping and having to start over. This forces me to leave the group because I don't want to force others to try over and over until I get lucky and don't crash. I tried three times and I crashed three times. So at this point I am now stuck with 72 days of game time and I can not progress the story.

I have tried all "solutions" that I could find and none of them work. I was excited for Endwalker and wanted to get caught up on the story while I had some downtime. However, if this is the kind of service that we can expect then there is 0% chance I will come back. I shouldn't be forced to play on a console just because the PC version is broken.
