RTX 3080 ti LHR speed bug

[munroc]

I have last nvidia driver, CUDA 11.5 and hashcat 6.2.4 version installed. I'm running on a RTX 3080 ti LHR. My issue is that hashcat is running insanly slow. For example if I run: hashcat.exe -m 100 -a 0 7e833a995c978d9037139017423f45aafc0e8449 rockyou.txt -O It takes 6 minutes to run, but if I run the same command on my 1060 laptop it runs in only 1 second.
Another weird thing that happens is, the first seconds when I run the command I get:
Time.Estimated: 0 secs 
Speed.#1.........: 12871.4 kH/s
But after 5 seconds I get:
Time.Estimated: 1 sec
Speed.#1.........:  2220.7 kH/s
If I keep pressing "s" (status) the Speed keeps decreasing.
I have tried with MD5 too. But same issue.
I takes 6 minutes to finish but it should only take less than 1 second to run. So something is very wrong :/
I hope someone can help me.

Yes, I can confirm. I tried version 6.1.1 and works fine. There is some glitch on last version.

Yeah,
 if it is win7, only 6.1.1 is normal,   6.1.2-----6.2.4 will cause errors
