Description

Testing trilium as replacement for logseq since a couple of hours. I've tried to make a canvas scheme, and the canvas began behaving strangely (letters disappeared once they were typed etc). I ended up not being able to modify the canvas, the mouse won't select anything in it. Everytime I double click, I get the following error in console:

In the canvas note, I cannot even select a tool to add text or an arrow. I cannot even use the export to disk / png button. Of course I can open a new canvas and everything works as expected.

I tried to save the canvas (export as json and reimport in a fresh Trilium instance, changing its type to canvas), the issue stays the same. I've also uploaded the exported canvas JSON to a validator which says everything is okay.

I'd like to recover the canvas (more for a proof of concept I don't lose data than for the actual contents which are about 10 minutes of work). Provided the export canvas json file as attachment to this issue.
