100% Flash memory used by system/proc folder - Oppo find X3 lite - colorOS 12

I'm currently facing this issue: after the ColorOS 12 update on my OPPO find X3 lite, my phone was showing the warning of flash memory full (128 GB). Even removing files, cache, apps and other stuff, after very little time it was showing the warning again. Long story short, I found that the system is creating multiple copies of the same folder under the path "system/proc/12566/task", there are currently 98 folders using roughly 1,3 GB each. Is it a system bug? Should I try to remove these folders? Anyone's already faced this issue by chance?
