Whenever I add looks onto an adjustment layer, my AE crashes.
I have a AMD Ryzen 5 PRO 5650U with Radeon Graphics 2.30 GHz processor and 16.0 GB (14.8 GB usable) RAM with 64-bit operating system, x64-based processor
Without actual crash info we can't tell you much, but just by looking at your super tiny screenshot I can tell that your system may not meet the requirements for screen resolution and the plug-in fails because it can't allocate its buffers or draw the designer window. You need to fix that.
