I clicked on the project tree while debugging and got this error :

I’ll probably need a bit more to go on, for this ☹

I tried to reproduce the problem but without success. I get more often Water crashes with application close while waiting for loading large wasm module. I will confirm it tomorrow, Carlo has my test project to reproduce other issues.

This happens when I start rebuilding of the project and then click on solution tree. I can reproduce it many times.
