Hi, I can't really reproduce it but my js error tracking service is reporting this error since I upgraded survey-react-ui from 1.9.77 to 1.9.78.

at ./node_modules/survey-core/survey.core.js:23082:45) _this.container.children[0].focus();

Specify your

browser: Chrome
browser version: Chrome Mobile 111.0.0
surveyjs platform (angular or react or jquery or knockout or vue): react
surveyjs version: survey-react-ui@1.9.79

@joker-777 Could you please try the latest version 1.9.80? I remember to fix something similar couple weeks ago?

Thank you, Andrew

@andrewtelnov Thanks a lot for your reply. It still happened with 1.9.79 but I haven't upgraded to 1.9.80 yet. I'll let you know once I upgraded it.

@joker-777 I'm afraid upgrading to v1.9.80 will not help much. Do you have any customization code that may cause this issue? Do you use any event handlers?

Thank you, Andrew
