you provide very little context... however:

there's a well known issue exposed in the help-patch of [pix_video]: 
whenever you (successfully) open a video device, it will attempt to 
change the number of the radiobuttons in the [pd properties] subpatch.


due to a bug in Pd's radiobutton, this gives a Tcl/Tk error iff the 
canvas is not currently open.


the solution is simply to not modify and radiobuttons while there 
canvases are not opened.


btw, this is unrelated to high-speed cameras and/or pylon,...

[PD] error using high speed camera in TCL

[Csaba Láng]

Hi list,

I am using 7 same cameras with th backend pylon.
For some reason pylon writes for the same camera Node not readable or:
Tcl) INVALID COMMAND NAME: invalid command name ".x562a9920.c"
while executing
".x562a9920.c delete 562a77785130BASE0"
("uplevel" body line 1881)
invoked from within
"uplevel #0 $docmds"

How can I fix it?
Any hints are welcome.
Best,
Popesz
