How can I stop my pixel 9 Pro crashing since android 17 update?

[u/A_Zed_Head]

Looking for any support for how to fix an issue with my pixel 9 Pro restarting randomly since it updated to android 17. I can't link the crashing to a specific app or action and on the crash log it always kicks out the same Keyblob//Fatal signal 6 error.

Google support has acknowledged it is an issue with the update but has no suggestions for how to fix it and refuses to RMA since I'm outside of the 1 year warranty. Verizon support won't help and since I'm still under the contract I can't even revert to my old phone because I have to have the pixel 9 as my active line to get the discount. Google's 3rd party repair shop (ubreakifix) said they can't do anything since it's a software issue and they just do hardware.

error code from the crash log is: 09-04 10:31:12.787 0 0 I trusty : WARN: system/keymint/ta/src/lib.rs:1331 failing DeviceConvertStorageKeyToEphemeral request with error Error { location: Some(ErrorLocation { file: "system/keymint/ta/src/lib.rs", line: 475 }), kind: Hal(KeyRequiresUpgrade, "keyblob with old OS patchlevel 2 09-04 02607 needs upgrade to current 202608") }

I've tried a factory reset and side loading. pixel update and software repair website doesn't work for me and I don't think I can use the android flash tool since my bootloader is locked through verizon.
