Don't have that hardware but here's my two cents:
https://linux-hardware.org/?view=computers&vendor=Raspberry+Pi+Foundation&model=Raspberry+Pi+4+Model+B+%28All%29These probes indicate that brcmfmac is the only wireless driver being used by most of these devices, and your brcmfmac seems to not be loading. I would start from the assumption you need to resolve a problem with brcmfmac instead of loading other modules. I searched the errors from your image to find other cases, but the results varied. Two had to swap a firmware file, one had physically broken their chip, and one thread discussed swapping their power supply or enabling overvolting to ensure the wireless card is getting proper power.
I would start by connecting your Pi via Ethernet or phone tethering and running your package manager's updates. You didn't give a timeline of how long you've used the device or when the problem started, so a reasonable assumption is that it started after an update, or this is a new device that has never been updated. Going online should also trigger firmware updates in the background from fwupd. This step is easy to do, and going online rules out software issues in the network stack having any part in the blame. Disconnect your Ethernet/phone, restart, and see if it works.
Next, you should try booting into a live CD and see if you can get this wireless card to work on another installation. This rules out catastrophic hardware failure and also demonstrates that you can reinstall if you can't figure out this problem later.
The power supply issue is plausible. Mess around with this if you don't have the official power cable.
Good luck!
