This looks like a symptom caused by an issue in the EC driver. The complete
error in your dmesg:

...
[   12.563832] ACPI Error: No handler for Region [ECSI] (000000007b8176ee)
[EmbeddedControl] (20230628/evregion-130)
[   12.564906] ACPI Error: Region EmbeddedControl (ID=3) has no handler

[   12.566187] ACPI Error: Aborting method \_SB.UBTC.ECRD due to previous error

[   12.569254] ACPI: \_SB_.UBTC: failed to evaluate _DSM
c298836f-a47c-e411-ad36-631042b5008f (0x6)
[   12.569259] ucsi_acpi USBC000:00: ucsi_acpi_dsm: failed to evaluate _DSM 2
...

The handler for the EC operation region is missing, which is very odd, because
the EC driver (drivers/acpi/ec.c) has clearly been loaded successfully based on
your the same dmesg output.

Can you also attach the acpidump output:

 % acpidump -o my_acpi.dump

The ACPI guys should take a look at this. I think this is to core issue here:
"ACPI Error: Region EmbeddedControl (ID=3) has no handler"

Thanks! I can see that "ECSI" EmbeddedControl OpRegion inside the scope of the
UCSI device in your tables, which should be fine.

I don't think we have a global handler for the EC OpRegion in Linux, which I'm
quite certain we really should have - just like we have for the other types:
SystemMemory, SystemIO, PCI_Config, etc.

This may actually be a missing feature in ACPICA, so other operating systems
may also be affected.

I'll see if I can get the ACPI/ACPICA guys to take a look at this.
