LowLevelFatalError - Detected negative delta time

Hi there,

after about 25 minutes, the build crashes with the error message shown in the picture after any change of map. It never happens at the beginning and never directly during the game. Using search engines didn’t help much - most threads I find related to “LowLevelFatalErrors” with “negative delta time” are from before 2010 and somehow related to Dual Core Processors. I cannot pinpoint anything that could cause that error. Nothing fundamentally different happens after 20 within the game logic and it happens at any graphic settings (low/high, frame limit cap off/on etc.)

AMD Ryzen 3600x,
RTX 2070 Super Founders Edition
, 32GB crucial 3200mhz
(no component has ever been overglocked)

Thanks for any answers in advance!
