Jquery stuff is not working after update to magento 2.4.4

Jquery stuff is not working after update to magento 2.4.4

Hello,

it seems that not all extensions are compatible with the latest magento update. I have an issue with the layered navigation.

The price slider is not rendered and in the js console I get the error "Uncaught TypeError: this.slider.slider is not a function".

The mega menu throws the following error in the mobile view "TypeError: a.ui.mouse is undefined".

Does anyone have an idea how to fix the js errors?

One other thing: I would like to remove the settings (currency and store switcher) from mobile menu. I tried to remove the blocks by xml already with
<referenceBlock name="amtheme.store.currency" remove="true"/>
But the items do not disappear. It would be great if someone could give me a hint how to remove the settings from menu.
