Applying virtual background error

We have functionality where it is possible to switch between virtual backgrounds.
This works as expected in all other devices but iOS. With iOS this errors appears:

Error applying filter for Stream str_id - AbortError: The operation was aborted.

This error comes when there is filter active and another filter is selected and code to switch filter is like below.

              async () => await'VB:blur', {})

After error, filter can be activated instantly in iOS device also. With other devices code above works, it removes existing filter and set a new one.

Can you spot what we might doing wrong here?

Edit: same behaviour happens only in iOS devices when filter is active and page is reloaded and we’re trying to apply the filter again.
