The deadlock happens if org-resolve-clocks is called automatically (for resolving idle time) while focus is in a EXWM-mode buffer. The result is that the focus is stuck with the EXWM-mode buffer away from Emacs and the user can not tell EXWM to change the focus to the mini-buffer to interact with org because org is grabbing all the input away from EXWM.
The only way out for the user is to kill the application in EXWM buffer from another ttyn terminal to be able to interact with org-resolve-clocks. See the issue discussion here as well: https://github.com/ch11ng/exwm/issues/921 Steps to reproduce: 1. Run X with EXWM as its window manager. 2. Clock in some tasks in an org-buffer. 3. Start some non-Emacs application (like Firefox)) it will run in an EXWM-mode buffer. 4. Leave the input for more than org-clock-idle-time. 5. org-resolve-clocks is get called and you get stuck in your EXWM-mode buffer till you kill the application somehow, because all you keys are all going to the EXWM-buffer and those that are supposed to go to EXWM to interact with Emacs is grabbed by org-resolve-clocks and ignored.
