C4D crashing without warning after sending render to PV

[FH]

Hi,
For a few weeks now Cinema4D is crashing without warning when render is send to PV.

I'm using C4D R20.059, with Octane 2020.1, as well as a slave computer with the same Octane version.
Windows is up to date on both machines and Nvidia drivers too : 442.92

Sometimes the rendering would go through without problems, but every 3 or 4 render sent, C4D would crash.

Is anyone experiencing the same issue recently ? Is it because I am using 8k hdri or millions poly objects (only one in my scene tho) ?

Config :
i9 9900k
64Gb DDR4
RTX 2080ti + Slave node 2x1080ti

Please find attached the last bugreport file.

Thanks

While rendering which scene?

While rendering which scene?

Pretty much any scene... From 9Mb files to 150Mb+ files, there is no specific scene where this issue is happening.

Could it be because my output resolution is 5k+ ?

ok please apply the instructions

Thanks, here are the logs.
I was just doing some adjustments, sending the scene to PV, having the render going on, and then another PV and it crashed.

No I haven't. Where can I find this option ?
