It seems that OnePlus is struggling to release a bug-free software update. The OxygenOS 11 for OnePlus Nord also came with critical bugs such as app crashing issues. Due to this, the company paused the rollout and released a fix for the issues in the form of OxygenOS 11.1.1.1. After this, OnePlus released OxygenOS 11.1.1.2. That too brought fixes for several bugs and the latest one is also of the same kind.
