The unwilling to travel bit refers to those with expired documents reporting such, why that is the case I don't know. It goes on to say the officer will reopen the application which suggests the application will be reconsidered to some degree or other which is a risk. The part about valid COPR and PRV makes it clear that they want you to travel before your documents expire. Personally I would travel if you can, who knows how long things are going to be like they are or if they will get worse.

Approved permanent residence applications (COPR and PRV)
Permanent residence application approval procedures (for finalized applications) and refusals (for reasons unrelated to the disruption of services), may continue.
Permanent residence applicants who are in possession of a confirmation of permanent residence (COPR) and permanent resident visa (PRV) and inform us, by submitting a web form to IRCC, that they are
unable to travel within the validity of their documentation should be processed as follows:
- Valid COPR and PRV: In an effort to reduce the number of cancelled COPRs and PRVs, a note should be placed in the file explaining that the applicant is unable to travel, and the file should be brought forward to the expiration date of the COPR and PRV. If the applicant informs IRCC that they can travel prior to the COPR and PRV expiration, they are encouraged to use their existing COPR and PRV to land.
- Expired COPR and PRV: If the applicant informs IRCC via the web form that they are unable or unwilling to travel after the expiration of their COPR and PRV, or if they are unable or unwilling to travel prior to expiration, officers are to re-open the application, and it should be brought forward for review in 90 days."
