IDE crash when visual designer is open

[User_Russian]

If you run the program when you open a visual designer of windows, IDE crash.
I'm tested on Linux Mint 20 x64 and Raspberry Pi OS.

Confirmed: if you open the FD while a program is running from the IDE, the IDE crashes (1 second later).
Does not happen under Windows.
Not a PB 6 bug, same thing with 5.73 LTS

(That said, this is a rather rare use case.)

Seems to work as expected, can anybody confirm ?
