Short description of error
When a render is in progress, if I press J a few times to cycle between render slots, Blender wil crash.
Exact steps for others to reproduce the error
Switch from Eevee to Cycles
Press F12 to render
In the render view, press J to switch render slots a few times while the render is in progress; Blender will invariably crash after doing this a few times (sometimes up to 10-20 times, sometimes faster).
