Thanks @mike skummer it helped me

I think we got the same problem

yeah...

that calms me a bit since if there are some users... it ll get fixed not too late

I'ma try reinstall minecraft this time erasing settings and other stuff... I found a crash report even if there's no crash message. I'm sorry for this, last time I searched for stuff in minecraft folders was long ago, I will see if this fixes the issure...

It came to my mind that optifine settings file broke the game

didnt work

I tryed to open othr versions. They all crash the same way. No version works below 1.13

feel dump for not finding the error report... hope it helps a bit

Not at all... Does Ubuntu 18.04 look like windows?...

Game bar of "loading" gets to 100% but the game never starts

Lighting doesn't only glitch sounds when to many at the same time. Check the issue again about lightnings: toggle storm and listen to them. They go well 60% of the time but sometimes sound is just cut. I mean all is good but some of lightnings sound as if you get the audio and click the stop button.

-it is supposed to all server hear one lighting?
