Hi, I faced the same problem, did you manage to solve it?
I have been trying for 6 hours, I watched tutorials, I tried tlauncher.org helps and I even tried fixing it myself too. I even downloaded beta tlauncher, cleared files and I redownloaded Tlauncher and java too but nothing works.
I really wanna play minecraft again, please help

If you are playing newer snapshots, This was a recent bug in the 17w14-16
They seem to have finally fixed it in 17w17a/b
It seemed to be related to a number of new additions like advancements and parrots.
Update your server_jar and your minecraft client to 17w17b (current)
If you are getting this issue on 1.11.2 release. Then open a bug report at bugs.mojang.com
Ive experiencing some problems with the launcher, it gives some flickering error saying java.lang.nullpointerexceprion: null. I cannot close this window without using task manager by force closing it. I already did the solutions from the website you have given.
And also a window pop up when I install tlauncher saying "Could not open the destination file for writing"
Any other solutions, other than giving up and being depressed?
(BTW: sorry for my grammar, and also thank you to those who will reply to this post)
when people try to connect to my server, they receive this error messageinternal exception java.lang.nullpointerexception can not invoke "net.minecraft.nbt.compoundtag.m_128459_(string)
i also received this error message as well but during this test for some reason it let me join the server, i've tested this out on singleplayer as well and the world works fine nothing seems to be corrupted it just doesn't work for the server.
we've also made multiple worlds for this specific pack i've made and they all have had this problem, randomly sometimes people will be able to join and play normally but other times they get this error and they cant play.

A NullPointerException means that one of the variables you are passing is null, but the code tries to use it like it is not.
For example, If I do this:
Integer myInteger = null;
int n = myInteger.intValue();
The code tries to grab the intValue of myInteger, but since it is null, it does not have one: a null pointer exception happens.
What this means is that your getTask method is expecting something that is not a null, but you are passing a null. Figure out what getTask needs and pass what it wants!
This error occures when you try to refer to a null object instance. I can`t tell you what causes this error by your given information, but you can debug it easily in your IDE. I strongly recommend you that use exception handling to avoid unexpected program behavior.
