Description

Hello,

An error will pop up when the program closes.

Sometimes it only appears for a fraction of a second, barely noticeable. Sometimes it will also appear for a few seconds. I've copied it a few times and the bug always writes the same thing.

I know the program does not limit it, but it did not make the mistake before.

I'm sorry, I do not know exactly when it started, but it's been a longer time (definitely it started in the version of the end of January)

Please repair.

Thank you
