when select text the windterm execute ctrl+C automatically

When windterm runs for a while, this situation will occur: when you use the mouse to select text in the terminal, the terminal will automatically execute ctrl+C to terminate the current process. After restarting the machine, it will be normal. I now have this problem almost every two days and have been troubled by it.

the OS is win10, version is the latest 2.7.0
the screenshot is like this:

No source file, test, or entry point is identified. Reproduce the behavior on Windows 10 with WindTerm 2.7.0 after it has run for some time, then trace the mouse-selection and Ctrl+C handling; done means selecting terminal text no longer terminates the active process and the behavior is covered by a regression check.
