Here we go... the "bricked" definition police...
Normally that sign means that it can't find the System to Boot. Booting into Recovery and reinstalling it might help and if that partition isn't available, then Internet recovery should help.
Because not being bricked is not being bricked. I never ask for a person to give the definition after that they state it wrong, it is just don't state it wrong to begin with to get attention.
One may call it, a nothingburger brick, it could go away in about a week.
Either way, nothing or not, I would take the steps mentioned above with properly resetting PRAM and SMC witha solid reboot after each one.
Run a hardware test just to rule out an immediate drive failure or RAM issue.... stranger things have caused that ghostbuster symbol so it is difficult to rule it out exactly until you can rule it out.
If hardware all passes, there are some essentially first aid style tests you can do in Terminal from Recovery Mode.
My main go to would have macOS on an external drive that is large enough to copy over ALL data if necessary. Boot to the external, then check if the internal drive even shows up in Finder.
For me, if it does, then I run CarbonCopyCloner and clone that entire drive, 2ndly, just simply copy any Apps, Documents, Photos, Music, Movies, anything of importance off of the potentially trash drive.
Once all data has been copied over and verified that it is actually moved and usable. Do a erase disk from Terminal to wipe that entire internal drive/it's partitions and everything out. Then let whichever version of macOS you want to use, rebuild how it wants. See if the machine boots on it's own, update to latest and verify things work prior to moving any sensitive data back. But still keep the data that was backed up, put a sticker or tape on that drive with the date, file it away in a cabinet, drawer, or closet.
Call it a day, it'll be done in less than a week, shouldn't have to be shipped off, and can be done while watching TV with the rest of the fam if that's a thing ya'll enjoy.
