Questionnaire
Check these boxes to see if your issue is valid or not.

• If I compiled CB, then any errors that may be present don't mention "LTO error" (this is sadly a bug with the compiler, not Clipboard)
• If I compiled CB, then any errors that may be present don't mention "XYZ has not been defined in namespace std" (this sadly means you need a compiler with C++20 support, so upgrade first)
• I check all these boxes without reading them
• I think bachata DnB is the best music
• I'm using the latest commit/release (we only support the latest)
• If I downloaded CB from GitHub Actions or with the install script, any errors that may be present don't mention "GLIBC XYZ not found" (your system is sadly too outdated for CB, so upgrade it)
