ssd 4tb not compatible with Precision 7540?

Dear reader,

I bought a Lexar NM790 4TB M2 ssd for my Dell Precision 7540 laptop. I mounted it in the third free slot. The other two are in use by the system-drive 500 gb and a Lexar NM790 2TB.

The 4TB SSD seems to be incompatible. Every time I try to start-up Windows 11 gives a Blue screen.

Drivers are up-to-date. The 4TB ssd shows itself in the BIOS.

Any thoughts?

Thanks!
