Please help me if possible, how to get rid of this.
This is a known issue with python>=3.10.2 and requests-cache<=0.9.0: https://github.com/requests-cache/requests-cache/issues/501
The solution is to update requests-cache to 0.9.1 or later.
Updating requests-cache to latest version fixed the issue. Thanks to @JWCook
