How To Read Crash Reports?

[SIN1K]

Hey guys, 

Title pretty much says it all. Just updated to 1.17.8 and updated couple mods to this client version too but noticed a crash on loading the game. I have no clue how to read this crash report to debug it so I can fix the issue.

It should be noted, obviously, the crash is occuring due to mod conflicts as I was fine playing with all the mods I have on 1.17.6 prior to the update of the client and a few select mods.

If you could help me understand how to read this crash report so that I can pinpoint the issue, that would be amazing.

Appreciate any and all help given my way 

Here's the crash report below:

Crash reports like those are usually more useful to developers than users.

What you could do is look at the patch note and see if any of your mods does impact a new feature or a bug fix, or wait for the mods to be patched for 1.17.8.
Or disable all your mods and load them one by one to spot the bad apple.
