Console Becomes Unresponsive After Attempting to Open an Oversized Variable

[SimpleZion]

After Spyder 6 fails to open a variable that is too large, the entire console becomes unresponsive. From then on, no code can be run, which is extremely troublesome!!! I have to restart a new console and re-run all the previously executed code. This issue has already wasted a huge amount of my time.
In Spyder 5, it used to warn you that a variable is too large and ask for confirmation before opening it. But in Spyder 6, just clicking the variable immediately triggers the variable viewer, without any prior warning — and the console crashes so easily!
Why is it getting worse with every upgrade?!

Hey @SimpleZion, thanks for reporting. This seems like an unintended regression (we usually do big improvements and refactorings in major versions, so some things can break in the process).

Please post a simple code example that generates a big variable for you so we can test it in our side and try to fix this problem for Spyder 6.

You can open the “data” variable and try it.

import numpy as np
import pandas as pd
data=pd.DataFrame(np.random.rand(1000000,1000))

Console becomes unresponsive later and I have to restart.

@dalthviz, could you check this one too? Thanks!

Gave this a check locally and I think I was able to reproduce. Seems like indeed a direct attemp to open the oversized variable is done and when that fails, the used resources like RAM are not being restored inmediatly causing the need to restart the console kernel/close the console to release the resources 🤔
