"Unrecognized block header in profiler data file, stopping deserialization" error is shown and no more profiler data is recorded when the Player is connected and profiler recording is enabled/disabled few times

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Go to File > Build Profiles
3. Enable "Development Build" and "Autoconnect Profiler"
4. Build and Run the project
5. Once built, observe the data is being recorded in the Profiler
6. In the Profiler, click on the recording button 4 times (to disable - enable - disable - enable)
7. Focus back on the Player and observe the Console and Profiler

Actual results: "Unrecognized block header in profiler data file, stopping deserialization" error is shown and no more profiler data is recorded

Expected results: No error and the profiler data continues recording

Reproducible with versions: 2023.1.0b1, 6000.0.66f1, 6000.3.5f1, 6000.4.0b4, 6000.5.0a5

Tested on (OS): Windows 11

Notes:

• Could not reproduce on macOS 26.2
• It appears to be caused by the fact that no data is gathered after the first re-enablement
