How can I safely exit Guided Access on my iPad Pro?

After I set the password for Guided Access mode in iPad Pro, I activated Guided Access mode in another app. When I tried to exit, I found that the on-screen keyboard for entering the password was incomplete and I was unable to enter the password effectively. This made me worried because I was worried about losing the data in the device, which was very precious to me. Later, I solved the problem by force restarting the device. I hope Apple can fix this bug so that other users don't have the same bad experience as I did. My device is iPad Pro 12.9 (3rd generation), iPad OS: 18.3.2 (22D82), model: MTJF2LL/A
