This means the GPU driver on the device you’re running on doesn’t provide any details into why it failed.
The filed shader is the postprocessing one - try disabling postprocessing in the project.

Thank you for your reply~
After testing, I found that ‘glsl link failed’ would occur on random shaders. The log I captured this time is from postprocessing, but it could also happen on the shaders I wrote myself.

This is a message from the GPU driver. If it happens on random shaders, there may be a problem with the device you have.
