Crash when switching to user profiles

Pepp

Hi, I need your help please. I have a Pixel 7, with GraphenOS. It switches perfectly in the user profiles I have created, but only if no pin number is stored in the respective user profile.
As soon as a user profile has a pin and I go into this profile, the phone switches to the main layer and sends a crash report. If I repeat this and remove the pin in the profiles, it changes as described without any problems. Have you also had a problem like this?
Greetings.

Same here on 6a. And many others.

Recently I even raised a bug ticket on github which was closed immediately (only occus in rare combination of settings they said). Nontheless there was an update last month which adresses this issue. Unfortunately this update could not solve this issue for me.

However, what helped for me (luckily found an another thread here): You have to lock current profile before swichting to another user profile. Always leave a profile with "End Session" (long press on/off button).

Thank you for your answer and your explanation.
I have tried it, it does not work. Maybe I am doing something wrong.
If I press and hold the on/off button, the window appears with the options off/restart/emergency/lock. Do you mean this window in which I should press Lock?

Hello, I think I know what you mean now. I don't have a choice on the main profile to quit or end session only to lock. What can I do?

Sorry for not being precisely. From main profile use "lock". From other profiles use "Quit Session".
In user settings "Delete Guest Activities" (don´t know exact EN translation) is activated.

Hope that helps ;-)

Thank you.
I have learned that it helps to deactivate the developer options. It has an enormously positive effect on the stability of the system. I use this trick and yours. Thank you. I can continue with that for now.

notsure

I have pixel 7 which started crashing on selecting user profile that has pin after update to build #2025050700
As described above, after long press and selecting [lockdown] from owner session, it is possible access to pin protected user profiles. Thank you for posting workaround.
