The function or variable 'cvxobj' is not recognized

When I install the cvx2.2 toolkit in MATLABr2022b, I get a unexcepted error “The function or variable ‘cvxobj’ is not recognized”,How can I solve this problem?

Never seen this before. Does it happen on installation, or when trying to run a CVX problem?

Perhaps try installing CVX 2.2.2 Announcement: CVX 2.2.2, the first "full" open-source release .
