I had absolutely none of those issues, I am running the absolute latest release (evolution_raven-ota-tq3a.230605.012-06281958-unsigned.zip --> released a few hours), and its FLAWLESS!!! More info would help, I.E. what did you come from, how did you take the update, ETC., because it works great here. The difference may be that I didn't take the OTA, I sideloaded the ROM from PC, then did MAGISK and fastboot'd the new boot.img (ROOT'd MAGISK boot).

I NEVER sideload MAGISK (EVER), I ALWAYS patch boot.img, then fastboot, PERIOD!!

I would get rid of that method, it only errors or has issues for me (sideloading MAGISK). Instead,

always patch the boot.img for the ROM

, then fastboot it! This is a sure-fire method, and a flawless step that never fails for me.

Make sure you have flashed the matching boot.img, vendor_boot.img, and dtbo.img to the right partitions for the latest ROM release (dev provides them in the DL links). I always redo them with every update and it always works flawlessly for me! IDK if its needed every OTA, but I do it, and never have a hiccup!

Here are the fastboot commands to flash the images:

fastboot flash --slot all boot boot.img

fastboot flash --slot all dtbo dtbo.img

fastboot flash --slot all vendor_boot vendor_boot.img

In MAGISK, you need to patch the ROM's boot.img (evolution_raven-ota-tq3a.230605.012-06281958-unsigned_boot.img) --> first option --> 'select and patch a file', then transfer the NEW boot.img (MAGISK'd) to PC and fastboot the NEW MAGISK boot.img. Here is the command to fastboot the patched MAGISK/boot.img:

fastboot flash --slot all boot ****MAGISK.img

If you do the MAGISK install this way, and always patch/fastboot, but never use sideload, it should always work for you. Assuming you have no partition damages (or any unusual damage elsewhere), you should be ROOT'd and boot with no issues. Once booted with ROOT, go into themes and tweak the themes and settings to fix your 'home controls'. Gain ROOT prior to fixing themes, I suspect you have custom themes loaded, but lost ROOT (with the update). OTA and any updates that overwrites the MAGISK boot.img, will lose ROOT. This is normal, and always happens when the boot.img is overwritten (with stock ROM boot.img), from the ROM OTA update. I suspect themes are failing to work properly (due to lack of ROOT to function). Fix ROOT first, then fix the theming options and let us know the outcome!

You may also need to redo your 'system gesture' and set/reset 2 / 3 button navigation' but IDK based on little to NO logs or evidence or even a description of what 'doesn't work' so this last piece is a guess based on lack on information. You mixed two or more issues into ONE post asking for help, but you neglected everything we NEED to help you (logs, description, install/OTA process, ETC., what version did you OTA from, and so on).. Without this CRITICAL information, we are left to guess, or just answer every possibility which doesn't help anyone.

For others, the latest release work great for me, I have no issues and I have tested everything I use/need (most phone services with stability testing)! I found ZERO issues whatsoever, nothing but stable Android! Well done AnierinB, and thank you!!!!
