Character becomes unable to do anything but walk

Happens sometimes, especially during multiplayer, that my character becomes unresponsive for anything but WASD movement and exactly 1 weapon swap to weapon set 2.
Happened on the following occasions:
- Other party member died
- Party member joined map
- I opened a breach (in multiplayer)

I also cannot dodge roll and I cannot pick up items. Literally any other character action but wasd movement is disabled in this case until I either relog or die and respawn.
When I try to put down a portal in this state, the game tells me that I am in an area where I cannot do that, even though I am just right in the middle of the map (maybe that hint helps).
I can open menus and interact with the rest of the UI though.

I am always the host.

This happens at least once a day and has gotten me killed multiple times now. Really annoying at level 97.

Found this thread from half a year ago:

Could you please look a little harder?

Happened again, this time outside of multiplayer.
I freed an essence monster with a vaal orb.

Here is also a screenshot show casing how I cannot use a portal in this state:

Happened again, this time in multiplayer.
The trigger was that the breach just closed.
Maybe it has something to do with pressing the loot pickup button? I noticed that I might be in the process of looting whenever this happens.
I have a German keyboard layout and my pickup button is the one right next to the shift key: <

Happened a bunch more times, each resulting in a death.
How am I supposed to get any levels when I die every 5 maps because my character is bugging out?

Could I maybe get some staff response to this? I found threads of other people experiencing this bug as well and I also know some other people who have had this bug. This is gamebreaking.

*BUMP*

Also I think it might have something to do with the thawing charm. I noticed that whenever I have this bug, I think that it has just triggered.
