Hi @chernikovva,
Assuming that with “after the update” you mean WordPress 6.1 which released recently, I’m testing the block with WordPress 6.1 right now and I can select/deselect options just fine.

For the test I used a stock WordPress theme (Twenty Twenty One) and the only active plugin was WordPress Popular Posts. I found no problems with the block (as I already stated above).
Maybe something went wrong with your WordPress update? Or even a conflict with other plugins? Try following these troubleshooting instructions to see if you can find out what’s going on.

@hcabrera one day I updated the plugin, previously updated vp. Strangely, the problem went away when I replaced the plugin widget.
The widget that stood before did not work.
Thanks for the update, @chernikovva. That’s pretty odd, haven’t seen that kind of issues before but I’ll keep an eye out and see if I can reproduce it in the future. WordPress usually handles updates pretty nicely so no idea what could have happened.

@hcabrera It really looks weird. But wordpress has problems with /json/ files. I have tried several options. Even reinstalling the plugin itself.
But the simplest and most effective method was to re-create the widget.
