Pc and Fortnite crash?

The day before yesterday I built a new PC. The following parts are installed:

-Ryzen 7 3800XT

-Corsair Venegeance RGB PRO black DIMM kit 32 GB DDR4-3600, Cl18-22-22-42

- MSI MAG B550 Tomahawk

-Corsair Hydro Series H150i Pro RGB

-be quiet! Straight Power 11 850W ATX 2.4

-Corsair Force Series Gen.4 PCIe MP600 1TB, M2

-MSI Geforce RTX 2070 Super Gaming Z Trio 8GB GDDR6

-Corsair iCue 465X RGB white

Now to my problem: My CPU showed a maximum of 72 degrees on HWiNFO at full load in Cinebench, my GPU 40-50 degrees. Now after doing the tests, I thought my PC would pack Fortnite to 1080P 180Hz, but I had a crash every few minutes (error code 0x00000119). At some point the PC crashed, it said: A problem has occurred on the PC, it has to be restarted. It collects some error information and then reboots.
Could it be due to the temperatures or is the problem something else, what can I do now and someone could possibly look over it

Values during the crash in Fortnite (1-5 / 10 images)

Test your GPU at full load.

Preferably use FurMark for this.

I took a screenshot of the FurMark values (I still have MSI Afterburner running in the background)

Ok fixed the problem. Had a defective ram module.
