Ipad freezes during sidecar-use

I am using macbook pro, sidecar with my ipad pro.

In beginning it works fine, i did not have a feeling of freezing happening in first few days.

Then ipad start to freeze minutes after connected. This happens quite frequently now, that i cannot even trust to use this function. In this time of covid-19 home office period, i really need this function to have a second screen.

One existing question is not active anymore.

I am facing the same problem.

Both cable connection or bluetooth.
