Controll issues

I have a Problem controlling my Charakter.
it happens sporadicly but quite often.

When im in a map moving around suddenly i can't use any of my skills for 2-3 seconds. after that it returns to normal.
For example: I go into a cleared Map, where no Monster is alive, shield charging around for 20seconds, blinking with frost blink, using all my Skills i can press, everything is fine. then suddenly i cant press any skill, it just does not register. after a few seconds everything is back to normal...
Leftklick is Molten Shell or Move Only, doen't make a difference.
Every other skill "Allways Attack without Moving" activated

Things i tried:
Changing from WLAN to LAN
Changing Networkmode from Lockstep (Auto) to Predictive
Changed to multiple different POE Servers
New Keyboard / Mouse
Switched through every USB Port i have
disconnected every device i don't need

probably some more things i forgot allready... i have no idea what this can be.
I only have this Problem in POE, no other Game or Windows application makes any Problems. Please Help.

Some of my Hardware:
AMD Ryzen 7 3700X 8-Core Processor 3.60 GHz
RTX 2070 Super
32GB DDR 4 Ram
Windows 10 Home

System and drivers are up to date

press F1 ingame and watch which part of the graph goes up in the upper right corner of your game overlay

all graphs are fine, nothing spikes when this happens

No one has an Idea? :(

thing is, with switching to predictive network mode, you have ruled out all network related issues since the game should have let you move even if there is no data exchange with the server.

you changed the input devices, so no hardware issues there.

you probably checked the input drivers / mouse drivers for not working scripts.

you probably disabled/uninstalled any security software

do ingame animations play while you can't move?
does the f1 graph update itself?

can you look how the cpu/gpu load is while this happens? if it's normal, it's input related.

thx for the reply,
everything is normal, while i cant use the keyboard keys. (i can move fine with the mouse all the time)

No spikes in any usage graphs
GPU fine
CPU fine
RAM fine
Latency is between 8ms - 12ms

the whole game works fine, i just cant use my Keys for a few seconds.
still searching for new ideas (even obsure ones)
now i will try different rendering versions an Vsync
(165 Hz Monitor with Gsync)

different rendering options and Vsync did nothing.
I noticed something strange now:

All Keys that get locked are active skills with some kind of animation!

Inferlan Cry / Shield Charge / Frost Blink -> all blocked, cant use them

Blood Rage what is without animation i can use just fine.
And i switched the hotkeys, so there cant be an issue.

The Problem is that all Skills with an animations are getting blocked...
i Have no Idea what that is

lookup the game's logfile in c:\Program Files (x86)\Grinding Gear Games\Path of Exile\logs\client.txt

try resetting the input settings by renaming c:\Users\vio\Documents\My Games\Path of Exile\production_Config.ini before you start the game.

it resets everything but you can replace the old version later on.

given you're on the standalone version: if it's really animation related, check your resource file by running c:\Program Files (x86)\Grinding Gear Games\Path of Exile\packcheck.exe when the game is not running

and do a malware check if a program is watching your keyboard input and messing with your keyboard driver?

Thx for the inspiration.

im on the Steam Version. i checked the files there, no problem found.
deleted the config, the Problem stays.
