Logitech Control Center (LCC) is not compatible with macOS 11 (Big Sur) due to a new Apple policy that requires significant changes to how our software works.
Certain LCC devices will be supported in an upcoming Logitech Options release, while others will not. You can find more information in regards to this below:

As some users may have discovered, it is possible to disable core macOS 11 (Big Sur) security features, specifically System Integrity Protection (SIP), to allow for LCC to run.
Logitech advises strongly against this, as the macOS System Integrity Protection (SIP) protects the entire system by preventing the execution of unauthorized code and leaves your computer vulnerable to malicious code.
