1.12.2 vanilla client crashing upon startup, could be on mojang screen or before selecting singleplayer or multiplayer, unable to toggle windowed mode without it not responding. Here's log: https://paste.ubuntu.com/p/MTRDGq4jQs/
i have literally only seen you comment this one exact post. are you a bot or just spamming another thread? Point 2 on that thread doesnt even correspond with most threads you link to it.
Tails1 is a very long term person who is basically sick of seeing the same errors posted over and over, especially when a vast majority of them can be fixed by reading the READ THIS post at the top of the forum. the reason he replies like that is that the user has not said he has done it and it usually fixes the issues.
as far as this particular issue goes the OP should try updating java which is something you should always do before asking for help
i literally have done all the things i can do. like, im 20 years old, i know most of the fixes, and today it just started working again. i didnt do anything between the last crash and this morning, and sudenly works again.
edit: nothing on the tails1 thread had any effect on my problem. so, clearly my problem wasnt the "same error" as you put it. and i can tell it wasnt because i have never found a threat that relates to my crash. also, the READ THIS post did not help in any way, shape or form.
im not trying to sound rude, but "as far as this particular issue goes the OP should try updating java which is something you should always do before asking for help" - you say this like im thick. like i said, i had checked everything. it just started working today. (for no reason).
mojang actually autopushed a java update today for once because of this and similar issues, chances are it was a java issue.
