Windowed mode does not work

[Helioform]

It crashes when I try to set the game to windowed mode.

It raises an exception: "read access violation this was nullptr" inside this method:

void idVulkanBlock::Free( vulkanAllocation_t & allocation ) {
chunk_t * current = NULL;
for ( current = m_head; current != NULL; current = current->next ) { // exception here
if ( current->id == allocation.id ) {
break;
}
}

...
}

Hi, what's your setup? ( OS, card, driver ) Are you setting r_mode or other render cvars from the cmdline on startup? How are you going to windowed mode essentially?
