document.getElementById("icon_" + pickerId) is returning null and you are trying to get .className from null. This should fix your error.
else {
if (myOwnFormat == 'HH:mm:ss' || myOwnFormat == 'HH:mm') {
if(document.getElementById("icon_" + pickerId)) {
var className = document.getElementById("icon_" + pickerId).className;
$("#icon_" + pickerId).removeClass(className).addClass("hcm-grid_calar_saat");
}
}
return myOwnFormat;
}

As part of increasing the Security features as part of Spring 22 Release, Salesforce has moved few components to Private API. resulting which this error is being popped-up. Unfortunately this was not mentioned in the release notes, but you can find it in the console with "sfdc-lightning/charts/vbar.js has been deprecated. Please update your code to use lightning-vbar-chart".
The workaround would be using the standard 'Report Chart' component in lightning page.
