System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 527.37

Blender Version
Broken: version: 3.5.0 Alpha, branch: master, commit date: 2022-12-23 00:56, hash: f803a0a95b
Worked: 3.5.0 Alpha, branch: master, commit date: 2022-12-21 20:25, hash: cef5841e12

Short description of error
When the Drivers Editor loads/displays existing driver information Blender crashes immediately. If the selected object does not have any drivers configured the Editor gets displayed as usual. However as soon as a driver is added Blender crashes with the following Error shown in PowerShell:

ERROR (gpu.shader): gpu_shader_2D_point_uniform_size_uniform_color_aa FragShader:
     |
92   |   if (srgbTarget) {
     | 
     | gpu_shader_colorspace_lib.glsl:11:0: Error: C1503: undefined variable "srgbTarget"
                                                                                                                                                                                                                                                                                                  Error   : EXCEPTION_ACCESS_VIOLATION
Address : 0x00007FF6B09AA40B
Module  : blender.exe
Thread  : 00002680

I'll attach the crash log generated by blender.

Exact steps for others to reproduce the error

Select the Default Cube (or any other object).
Open the Drivers Editor by right-clicking on any "drivable(?)" attribute and hitting 'O' or the "Open Drivers Editor" menu item (I've tested it with Location, Rotation and Shape Key Value).
Add a new driver.
It crashes.

The order of steps 3 and 4 can also be switched.
In the attached .blend file the a driver is assigned to a Shape Key of the Default Cube. The driver sets the X-Location of an animated Empty as the influence value of the Shape Key.
A prepared Blend-File:
Driver-Editor_Crash.blend
The crash log:
