Restore / DFU mode didn’t work (Boot loop’s happening)

My iPhone 8 plus (ios 13.5.1) acted up, phone restarted, tried recovery mode and DFU mode multiple times, stating an error , none of those solutions worked...

Recently, while i was using my iPhone, it suddenly restarted and turned off. I restarted it again to turn it on, and it was stuck on the apple logo. I restarted it again, and it still was stuck on the apple logo. Eventually, it went into recovery mode by itself. I did the whole process of recovery mode and it did not work. I downloaded the software update required for recovery mode, 3 times, and all of those 3 times it did not work, saying that there was an error. I had to restore (which basically means it deletes all your data and content) and that also did not work, saying that my iPhone had to be restored first for it to be restored. I came down to my last option, which was DFU mode. It also did not work. The software update downloaded and my iPhone displayed the loading bar that appears when updating iOS software, but it had no progress loading for more than an hour. I was using iTunes for it, and on iTunes it stated "waiting for update verification" at the top centre, and then eventually, after almost 3 hours, it said "iPhone has to be restored before it can be restored" just like the DFU error. Also It does constantly crash out of apps, apple apps, games, etc. It does not also not screenshot correctly either, only screenshooting half of the screen. If I try to turn on , the apple logo/boot loop is happening.
