My custom shortcut (configured with D-Bus) stopped working in some moment the past week. I had to change the custom shortcut to execute the command instead.
@RixzZ what is the final status of your change? How does it look like?
@mmahmoudian Can this be closed since it seemed to be a pamac issue?
Ok, after chatting on Slack with @borgmanJeremy and after multiple try and error, the following are the finding and the ultimate solution:
Jeremy suggested to dump the strings from the binary using strings:


and there it was, already in the binary file. But it was not in the binary Jeremy had. We then checked the sha256 checksum and they were different. I was clear that something is wrong/outdated with my binary. Surprisingly enough, I ran pamac update 5 hours prior to this.
Jeremy suggested to "clean install" flameshot:
❯ pamac remove flameshot-git
❯ pamac clean
❯ rm /usr/share/zsh/site-functions/_flameshot # because it complained once during installation that the file exists
❯ pamac install flameshot-git
and it worked fine and consequently the printscreen button not works fine (previously it was running the gui mode automaticallu and I had to activate it manually, butnow even when the D-Bus does not exist, the printscr spawns the D-Bus and then rung the flameshot in gui mode automatically:

P.s: pamac is doing what yay and similar software does, so you can practically replicate the solution with yay.
Thanks for the solution. I'll change it back to that.
I'll leave a screenshot of the alternative with the command anyway:

This kind of custom shortcut is added with the New > Global Shortcut > Command/URL option.
