maybe GTK returned a null pointer or something

**Describe the bug**
crash randomly, without an exactly reason, since hyprland updated to 0.5x.x . maybe when changing workspace, focusing or clicking on the clock module or just do nothing. with the log:
>archlinux kernel: waybar[469692]: segfault at 3 ip 00007f2007d8f5e1 sp 00007ffd651eb050 error 4 in libgdk-3.so.0.2420.32[545e1,7f2007d58000+82000] likely on CPU 7 (core 1, socket 0)

archlinux systemd-coredump[474225]: Process 469692 (waybar) of user 1000 terminated abnormally with signal 11/SEGV, processing... 

**To reproduce**
Steps to reproduce the behaviour, including a minimal config that triggers it:
- auto start waybar in hyprland
 - hl.on("hyprland.start", function ()
 hl.exec_cmd("waybar & hyprpaper & hypridle") 
 ...
 end)
- with waybar config like this
```jsonc
 "battery": {
 "format": "{capacity}% {icon}",
 "format-icons": ["", "", "", "", ""],
		"full-at": 98,
 },
 "clock": {
 "format": "{:%H:%M} ",
 "format-alt": "{:%A, %B %d, %Y (%R)}",
 "tooltip-format": "<tt>{calendar}</tt>",
 "calendar": {
 "mode" : "year",
 "mode-mon-col" : 3,
 "weeks-pos" : "right",
 "on-scroll" : 1,
 "format": {
 "months": "{}",
 "days": "{}",
 "weeks": "W{}",
 "weekdays": "{}",
 "today": "{}"
 }
 },
 "actions": {
 "on-click-right": "mode",
 "on-scroll-up": "shift_up",
 "on-scroll-down": "shift_down"
 }
 },	
 "hyprland/workspaces": {
	 "format": "{icon}\t{windows} ",
 "on-scroll-down": "hyprctl dispatch \"hl.dsp.focus({workspace = 'e+1'}\")",
 "on-scroll-up": "hyprctl dispatch \"hl.dsp.focus({workspace = 'e-1'}\")",
 	"format-window-separator": " ",
 	"window-rewrite-default": "",
	 "window-rewrite": {
 ...
 }
 ...
```
- do something else and wait for waybar to crash randomly 

**Expected behaviour**
works fine in hyprland 

**Environment**
- Waybar version: Waybar v0.15.0
- Installed from: pacman
- Compositor and version: hyprland 0.55.4

**Debug output**
- output in waybar 2>&1
