AI tool. When "Use generative AI" box ticked it wont Remove

That error message indicates an anti-malware package, a firewall, or a router somewhere on the network path between LR and Adobe's servers has incorrectly blocked the request:

"$$$/Clio/StatusCode/HTTP/Forbidden=We've encountered an issue and can't complete your request at this time. Please try again later."

(This error corresponds to the HTTP 403 Forbidden error code.)

Try these troubleshooting steps:

- Temporarily disable all the firewall/anti-virus/security services on your computer. If that solves the problem, then add a specific exclusion for LR to the services' rules.

- Connect to another network, preferably one serviced by a different ISP. E.g. a Wifi connection of a neighbor, a coffee shop, work, or your phone's hotspot. Sometimes the routers in these networks block some of LR's requests, especially in authoritarian countries like China.
