Random crashes and Apple logo on old iPad after lightning port repair

My quite old IPad (same one that had the audio issues after getting It’s lightning port repaired) has been experiencing some issues. Sometimes itl just randomly turn black, and display the Apple loading signal, then, it will let me resume using it. But this time, it kept doing it, it would not stop and whenever it did it would just go back to the symbol after about a quarter-second. The only way to fix the issue when it happens a bunch of times back-to-back is to force reset the iPad. Why is this occurring, and how can I fix it?

Original Title: IPad Random Crashes

(Also, it wasn’t the Apple logo, it was the Apple loading symbol, so the one that looks like a gear, sort of like this; ☀︎, with no center.)
