RT-BE92U Persistent Thermal Zone Faults

First post here so bear with me if I miss anything. Since purchase, my RT-BE92U has been plagued with the same issues others have posted here. Up until the new firmware version dropped, I was having constant problems with network stability. I am currently running the latest firmware version (3.0.0.6.102_37435) and a lot of the issues seem to have been resolved except for one. Before the firmware update, I was seeing intermittent thermal zone errors in the system log. Since applying the update, I am consistently getting the following errors that appear every 3 seconds exactly:

Jan 4 18:29:52 kernel: read_bpcm_reg_direct_keyhole: Wait for completion failed, devAddr 0x3, offset 24, idx 2
Jan 4 18:29:52 kernel: thermal thermal_zone0: Failed to get RAIL 0 temperature, ret=256
Jan 4 18:29:52 kernel: thermal thermal_zone0: Failed to get temperature, ret=-1
Jan 4 18:29:52 kernel: thermal thermal_zone0: failed to read out thermal zone (-1)

On occasion, the errors coincide with a drastic decrease in wireless network performance. Under normal conditions, when connected to the 6GHz network, my wireless network download speed averages around 1100Mbps. This will drop to a nearly unusable 2-3Mbps. The 2.5GHz and 5GHz networks also see a decrease in speed to around the same 2-3Mbps. Wired clients seem unaffected. Once I perform a hard reset to the router, it seems to correct the speed issue for a while, but the thermal zone errors continue to persist. This seems to happen anywhere from once a week, to every day. Performing a hard reset isn't something I want to nor should have to keep doing to correct the issue every time it happens. Please let me know if there is anything else I can do to stop this from happening. I am getting very close to returning this router and exchanging it for a different brand. Thanks.

Update: I ran the beta firmware version (9.0.0.6.102_37803) for about a week now without any real change. Still had random drops in speed and connectivity that would require a manual reboot. Saw that the new firmware version was released (3.0.0.6.102_37500),  so I uploaded that yesterday. As of this morning, thermal errors persist, except this time it's every second as opposed to every 3 seconds. This is going to be incredibly frustrating to troubleshoot whenever I have another issue cause the log is now going to be saturated with nuisance errors that I'm going to have to filter through. The router has been up for about 20 hours since updating the firmware. I'm going to continue to monitor and stress test the network for a few days before I send another report and message to @Aureliannn_ASUS . So far... not pleased.

I am on the latest too.  Turned the radio for 6ghz off on the wifi / professional tab - no change. Rebooted the router - 30 minutes of no thermal errors - but now the thermals are back - so have reset the radio to 'on'. No change
