Game Always Crash when have a killing streak in Delirium

First of all, I've been frustrating experienced for infinite loading screen issues which many people talking about for over 1 week since the update at 3/17.
Many times when enter map or back to the hideout,it just loading and never ends unless you Alt+F4 to waste your time and portals.
When it happens, don't know matter or not, I set loot filter to none and if lucky then maybe after some tries I can enter the map.
It's really annoying and frustrating but at least when entered the map,the game can be minimally played before.
But today the game is totally unplayable now. Finnaly after entering 4 scrabed map and killing lot mobs to push to about 5 or 6 stacks of delirium awards,game often randomly crashes by different error.
After disconnect every portals disappeared. Lost 20+ scrabs and nothing picked up due to the playstyle of delirium.
And sometimes I stucked in the map and can't go back to the hideout or can't go to the in-map portal like vaal side area.
Look at what the nonsense error messages.

I've seen so much variation of error messages today than the past several years I played this game.

Really, since the 3/17 update many people has problems with infinite loading, crashing, failed to join instance or whatever technical problems.
It's unable to normally play this game now but there not any response about these bugs from devs.
In real life I'm working for a website developing.
The reason why I mentioned that it's because when there's error make a part of customers can't use the site after an update, the first thing must be rollback to the last normally working version to make sure the site can be normally visited.
And no any response to customers should not be allowed.
