Dear colleagues,
I just installed root 6.40.02_1 in macOS 26.2 Tahoe, using ```brew install root``` . I would like to use the old mode TBrowser → ```root --web=off ```.
Everything seems to be working fine, except for TCanvas.
The TFiles, TTrees, tuples, etc are perfectely displayed. For TCanvas the program crashes:
```

Could someone please help me find where the error is coming from?
Thank you,
