Hi, during testing bake I switch to GPU and get strange results, fine, GPU does not work on GPU.
In my latest build I get a crash if I switch to GPU and try to bake.

Program received signal SIGSEGV, Segmentation fault.

I will test this with older builds for myself but may better to disable GPU for baking at moment.

Open file switch to GPU, bake.

Thank you and cheers, mib
