On logs, we can see : Received EAPOL-key M2 with invalid MIC from mobile xx:xx:xx:xx:xx:xx version 2 while it's valid MIC received on the few working client.
is it a bug ?

- You should go for https://software.cisco.com/download/home/284464214/type/280926587/release/8.10.196.0
to have the latest bugfixes and because the aireos based platforms are getting obsolete.

Before updating to 8.10 check that your APs are compatible with 8.10 on the Compatibility Matrix (link below).
If not then you should, at the very least update, to 8.5.182.12 (link below).
That kind of problem could also be a bug in the client so check that clients' OS and drivers are up to date.
What type of clients are affected and have they recently had any updates?

It can be a bug if no config was change but before, run a debug and share the logs please
