Upgrading from which version? v1.2.189 or earlier one?
Besides, Chromium 92 doesn't enable Vulkan renderer by default.

Did you try to reboot? Sometimes GPU is wedged without triggering GPU reset.
Does vulkaninfo and vkcube-display work fine on KMS console (e.g., ttyv0)?

I can't reproduce on Skylake with i915kms from drm-current-kmod with
either mesa-dri or mesa-devel. Tested with chromium-92.0.4515.159_1
after enabling Vulkan in about://flags and confirming Vulkan is used
by adjusting environ(7) with VK_INSTANCE_LAYERS=VK_LAYER_MESA_overlay.

Can you reproduce after downgrading just vulkan-headers + vulkan-loader?
vulkan-loader alone v1.2.189 -> v1.2.190 only had one functional change
https://github.com/KhronosGroup/Vulkan-Loader/commit/5661252091f2
while the rest are in tests which aren't hooked in ports/ yet.

For debugging the following may provide some clues:

$ vidcontrol -s 1 </dev/ttyv0 # or Ctrl+Alt+F1
$ sysctl kern.msgbuf_show_timestamp=1
$ sysctl hw.dri.debug=$((0x01 | 0x02 | 0x04 | 0x08 | 0x10 | 0x20 | 0x80 | 0x100))
$ vulkaninfo
$ sysctl hw.dri.debug=0
$ sysctl kern.msgbuf_show_timestamp=0
$ dmesg | sed -n '/\[drm/,$p' >/tmp/vulkainfo.drm-debug.log
