@Lutz_H: Your hang is due to reaching a breakpoint and is related to a plugin, but I wouldn’t know to which point it’s actually the plugin’s fault.
There is some operation from Limiter6_x64 (possibly quitting the plugin or closing the UI, releasing memory…), then a long series of operations from d2d1 and d3d11. The fault module is D3D10Warp.dll.
You could try and re-install the NVIDIA driver (custom mode → video driver only). You can also try an older driver revision.
I don’t recall seeing this call-stack before, but I resolved 3 dumps like this in the last 2 days, involving different plugins.
In case this started after Windows update, you could also try and roll back, then re-apply the update. Or run SFC /scannow.
The slow close on Mac is most likely something different.
