Finally fixed it by cleaning all the toolchains today.
check your paths in the staging_dir
cat: /media/emre/Linuxdepobuyuk/openwrt/staging_dir/target-aarch64_cortex-a53_musl/image/mt7988_tplink_be450-u-boot.fip: No such file or directory
do the fip exists ?? if not your problem happened much earlier in the build. to reveal the actual error, build with a single core (no -j) to avoid your logs from stomping on one another .

the reason its failing is obvious .. there should be evidence of why the mt7988_tplink_be450-u-boot.fip fails to build.
Need more info ...
I asked AI for this, it said that you should extract the FIP file first from a GPL code. But, how did I do that on AX80 EU without GPL?
ask AI ... it beats the heck outta me??
it may be suggesting you can extract the parts with uboot-tools, like mkimage -l firmware.img or dumpimge -l firmware.img. But fip will not be listed or dumpable with these tools.
And just so you're aware, AI is notoriously wrong .. or half right most of the time. I prove it wrong daily. ask it any complex code example that you are 100% sure of the expected result, 3/10 times totally wrong ..6/10 half right ...and 1/10 absolutely correct. Then throw openwrt related questions in the mix and it often just hallucinates.
IMO best way to find your answers is to ask the right questions here. Be as detailed as you can bare to be, while describing what it is you are trying to do. And probably most helpful thing, offer what you have so far, ie a link to a git repo to look at .. or post makefiles and code examples, point to where you suspect problems may be ..etc. Works for me anyway 
1 more tip, don't start multiple threads for the same adventure. This will not help get answers, it quite often has the opposite effect.
with that said, lets look at what you got, i love me a good old fight with uboot
Hey so I got a lot further than that, but I made a small mistake. I didn't test it with mtk_uartboot on ram first, just proceeded to delete u-boot. My compiled U-boot doesn't respond to my keystrokes here:

rut roo!! i hope you've got a backup, that one is foobar'd.
Uboot is not something to half assk, thankfully you've got the mtk_uartboot to attempt a recovery. On most units, thats a game over .. new paper weight. However, I have 0 experience with mtk_uartboot recovery so I am merely a spectator now.
Hopefully you can resuscitate it
mtk_uartboot is pretty easy, unless they've locked down the pre loader.
@bosukes you can follow the T-56 wiki, just use the corresponding BE450 files.

I may just need to get me one to play with. Not this particular unit but one the supports mtk_uartboot I just like the idea of being able to test uboot mods without going all in on each attempt. shoot me a msg if you have any suggestions for a unit .. that won't break the bank.
Sorry for hyjack.
three I know it can be used on, are Zyxel EX5601 and WX5600, Xiaomi AX3000T.
there are some additional units if you look at https://git.openwrt.org/openwrt/openwrt/log/?qt=grep&q=mtk_uartboot.

So u-boot layout and ubootmod is the same. So should I name it as ubootmod? It sounds way cooler am I right Why not do it with some style 
Chill out man I've totally destroyed my AX80 once, then somehow revived it again. Don't ask me how it would take 6 hours to tell you 
Yep, seems around ready. Wifi, macs all done
Don’t forget the OO.

What does that mean?
OpenWRT One.
When should I apply for PR? I think I need to test this for a few weeks to see if things go wrong or not.
Can't compile because of mbedtls 
Can you afford trying OpenSSL?
