Is there any way I can fix this issue, thanks

Is that a Barcelo chip? You may want to switch to a newer kernel, then. While it is pretty close to the Renoir and Lucienne chips, it is technically a newer-generation CPU, which means you want hardware enablement. In Update Manager > View > Linux Kernels, select the 6.5 branch and let it install. After reboot, it will default to that, but in case of issues, you can still fall back on the older kernel from the Grub menu. If you want to be doubly safe, make a Timeshift snapshot before doing anything else.

#

My guess is that the power saving modes are slightly off on the newer CPU, so it will sometimes dial the wrong one, of fail to wake the iGPU or something.

One question though, if a newer 6.5.xx kernel gets added to the update manager, will it detect and update automatically (apt) or do I have to manually install it myself.

Update Manager has this side tool I pointed you to, where you can select a different kernel to install and run. Once installed, it will of course be updated when it gets new releases. Make sure you occasionally run sudo apt autoremove to remove superseded versions. This will always leave the last few versions intact and is generally considered safe.
