Same here. On My OS: macOS Big Sur, 10.15.7 Xcode: 12.5 Safari: 14.1.1(16611.2.7.1.4) And I download at developer.apple.com/safari/download Safari Technology Preview 125,but same issue.

Hi,  I just found that many tabs in my Safari Web Inspector are no longer there.  For example, previously, I have the following tabs in Web Inspector: Inspector: Elements; Network; Sources; Timelines;  Storage; Graphics; Layers; Audit; Console; But now, I only have: Console; Sources; Audit; Does anyone know the root cause, and how I can restore the missing tabs? Thanks much. My OS: macOS Big Sur, 10.15.7 Xcode: 12.5 Safari: 14.1.1(16611.2.7.1.4) And I download at developer.apple.com/safari/download Safari Technology Preview 125,but same issue.
