Many ERC721/ERC1155 tokens, including well-known games such as Axie Infinity, have a pause functionality inside the contract. This pause functionality will cause the stopRent call to always revert and could cause issues, especially for the PAY order type.
When stopRent /stopRentBatch is called, it will eventually trigger _reclaimRentedItems and execute reclaimRentalOrder from the safe to send back tokens to lender.

This is problematic, especially for the PAY order type. Consider a scenario where the lender is not satisfied with how the renter utilizes their PAY orders NFTs. Now, when the lender wants to early stop the rent and calls stopRent, the call will revert, and the earning calculation for the renter will still be growing.
Consider decoupling the NFT claim from stopRent and introducing a timestamp tracker when the lender calls stopRent. Utilize that timestamp value when the rent stop is finalized and calculate the ERC20 reward for the renter.
