Area-51m R1, Thunderbolt 3 daisy chain problem

I have been trying to daisy chain using Thunderbolt 3.

I recently bought 2 ORICO 9558T3 for HDD extension.

The two external HDD unit works properly when separately connected to the Thunderbolt 3 port alone.

But whenever I try to connect the 2 units together using the daisy chain, I get BSOD driver_irql_equal_not_less
(storachi.sys)

I reinstalled Thunderbolt related drivers and all Windows updates and tried to make sure everything is up to date.

sfc scannow also showed no problems.

But the problem still persists. The exact moment the HDD indicators lights are on, the BSOD comes out.

The cables I am using out of the box Thunderbolt 3 cables provided.

When connected to one unit alone, I can access 5 HDD with the DP display function without any problems.

(both of the unit works fine this way)

I only placed one hard drive in each unit for testing (and also without using DP port). Both HDD are in perfect working order. If I connect them using other external docks. They also work flawlessly when the Orico connect to Thunderbolt 3 port of the computer alone.

the only problem is i could never get the two units daisy chain together successfully without bluescreen.

my laptop is alienware 51m. i9-9900k
(which supports thunderbolt 3)and my BIOS is latest, drivers are latest.

my system is windows home 10 64bit 21H1

I also read about storachi.sys is achi driver problem but I cant find anything related to my model to update the ahci drive from dell or intel website.

I consulted ORICO support saying this is a known issue maybe due to imcompability of the device chipset jmb585 with windows(maybe storage control drivers?) but there is no solution just yet. I also asked on microsoft but seems no one could answer as well

I also nocticed i had to remove all usb in order when connecting thunderbolt 3 device to be regconised. but all port works alright after i connected tb3 and then usb back on so its relatively a small issue.

for the moment getting rid of the BSOD storachi.sys would be great already. was wondering if anyone can give me some advices of what to do

thank you!
