Attempted Switch from DPC - Lenovo ThinkPad T590

Hello everybody.!

I would appreciate any help.

Started getting BSOD(Attempted_Switch_From_DPC) almost every other day and I've paid attention that this usually happens when laptop is idle.

My laptop is a month and a half old and it shipped with 8GB DDR4 ram soldered in MB(  base ram speed is 2666mhz but the real working speed that shown in Task Manager is 2400 because of CPU).

So I decided put extra RAM and it turned out that my laptop supports up 48GB RAM so I bought 32GB DDR4 2666 module from Samsung and got 40GB in total. I'm not sure maybe it's coincidence but I started getting these BSODs after these things: installing RAM, updating BIOS, updating Windows system (Cumulative update), using USB type-C adapter with 3-USB and 1-LAN output.  I don't know who the culprit is.

Here is the link to the DUMP file, data from Msinfo and Speccy -!AjF0Y2tXlq21hAVSSnCL8_95zho4?e=rt8xuI

My laptop is Lenovo ThinkPad T590

The experts here are going to ask exactly what RAM you used. But the obvious next step is to remove it and see if the problem persists.
