Android stuck in Boot animation after flashing GSI

I flashed Pixel Expirience GSI with TWRP by pushing it to the storage and flashing it as system img(with TWRP).\ The problem, it’s now stuck in a Google animation which came after the Sony logo.\ I would like to shut it down.\ I already tried adb reboot but error: device unauthorized And pressed the power off button 1 min and nothing happened.\ EDIT:\ I tried to install some GSIs, but they were stuck at the costum Romes Loading animation. 1. I installed the Firmware with Emma 2. Locked it to update to Android 11 and unlocked it again 3. Installed TWRP and booted into it 4. Wiped system and userdata 5. Pushed to system.img file from the custom rom to my device into /sideload/ 6. In TWRP install-System Image—> Pressed on the folder and on the system.img 7. It installed successfully 8. Rebooted 9. Stuck in Loading animation\ (PixelExpirience == A Google G with loading bar, LineageOs == The blue line with the bubble)\ No crashes or so what, it just hangs in there for ~20 min and than I turn the device off with volume(+) and Power button.\ I know Sony Xperia 1 is not officially supported for project treble, but since this thread(https://forum.xda-developers.com/t/mars_soms-v220313-pixel-expierence-android-12-gsi-patches.4097433/) requires Pixel Experience GSI I thought it should be possible to run GSI on Sony Xperia 1.\ Any idea what I might have donne wrong or are there other GSI roms I could try.\ *PixelEX = PixelExperience_Plus_arm64-ab-12.1-20220613-UNOFFICIAL.img 3.7 GB\ LineageOS = lineage-19.1-20220613-UNOFFICIAL-arm64_bvS.img 2.0 GB*
