Since somedays auto fill was not working on my computer (Ctrl+Maj+L). The problem was persistent with firefox & chrome so I deduced windows or other app blocks the hotkeys.
This evening at start, I noticed AMD Radeon Settings didn’t launch (no sounds, I’m using sound on HDMI) and by a miracle the Hotkeys (Ctrl+Maj+L) were working again. So I made the connection between AMD RADEON and my problem with autofill on Bitwarden (I updated my AMD Radeon somedays ago) : AMD software use the same Hotkeys as Bitwarden.
So the issue is on radeon’s panel " Gaming → Global Settings → Performance Monitoring → Toggle Performance Logging Hotkey" and to replace CTRL + MAJ + L by SUPPR or DEL.
