VK wait for febces casuing hard crash

[CJO Games]

The editor is continuously posting the above error (VK_Wait For Fences returned error -4). Its causing a hard crash at each instance to the editor the client and my PC. When the editor is restarted the work done up until that point is lost even when its saved at regular intervals.

What GPU? Is this new behavior?

Nvidia GTX1650 DDR6 OC 4gb CPU is Intel i3 10105f  RAM is Ddr4 16gb it's been consistent behaviour since launch and appears to get worse the more assets are placed in scene. It's not specific to Linux or Windows happens in both.

This is VK_ERROR_DEVICE_LOST:

It probably means the GPU is taking too long to complete the task.

I only get this if I run my laptop on battery power.

I'm not sure if this is irrelevant or not.. but I get this all the time on my radeon 6700 rtx.

I thought there was a regkey or environment var you could set to adjust the Vulkan timeout setting but I can't find it...
