BSOD DPC Watchdog Violation

For several months I've had a problem with recurring DPG Watchdog Violation blue screens, without understanding the cause. They had largely calmed down for several months, but resumed, which led me to completely reinstall Windows. However, shortly after installation, everything started up again as before.
I started collecting the dmp files, and underneath you have all the drivers implicated by the Windbg analysis.
My first thought was a hardware cause, but I ran all the hardware tests proposed in the bios. I also ran long stress tests on the chipset, processor and dedicated graphics card, with no apparent anomaly.
Impossible to find a precise cause for the problem, it happens just as easily on a PDF reader, Word, Firefox or even without software running.
