Intel(R) Ethernet Controller I225-V capped between 25 and 150Mbps

Hello, first of all I would like to point out that I use Google translate to write to you in English, sorry if some sentences are not clear.

I had fiber installed at my home a few days ago, but my connection is stuck between 25 and 150Mbps on my DESKTOP PC.

So I did several tests, on my LAPTOP, I have a 1Gbps connection with the same cable that i used on my desktop(my card cannot accept more)
I used several ethernet cables including a new one, I tried everything available on the internet regarding my problem, but I found nothing.

Only once, I forced a driver on my PC (with this tutorial: https://www.youtube.com/watch?v=JZy66e5zFCU), I have bluescreen then I had a 2.5Gbps connection, but upon reboot, the connection was back to around 30Mpbs.

Here is my configuration:
CPU: I5-13600KF
Motherboard: B760i Aorus Pro DDR4
32GB Ram
Windows 11 Pro version 23H2
Intel Ethernet version 2.1.3.3 (I tried all other possible versions)

Could you help me, I can't find a solution
Thx, have a good day.
