4x doesn't output, either silent exit or error

[teamolhuang]

With low thread counts it just simply exits silently without any output result.
With higher thread counts, it reports vkAllocateMemory failed -10.
Checking through AMD driver panel, VRAM was never full - at most 8GB where I have in total 16GB.

Same setting can be run stably under CPU mode, though takes much longer.

my rig:

i7-10700F
6900XT 16GB
32GB RAM

AMD driver has been updated to latest.

I experience the same problem, however sometimes my AMD Radeon Pro 5600M GPU works. It may be related to this issue with waifu2x-ncnn-vulkan port by @nihui.
