There is along-running post about this problem, dating from 2018:Thunderbolt Controller Error.
Thelatest entryfrom 2020-11-23 in the post says this:
The simple solution is to DOWNGRADE Thunderbolt Software by uninstalling the one from Lenovo (17.4.80.550) and install the latest version from Intel.com: 17.4.77.400 (Attached to this message)
NOW you can install the latest Thunderbolt firmware from Lenovo, but DO NOT re-install Thunderbolt Software 17.4.80.550 from Lenovo.
Make sure to DISABLE automatic updates in Lenovo System Update & Lenovo Vantage to prevent this from re-occurring.
Intel Legacy Thunderbolt Software TBT_Legacy-Win10-64-17.4.77.400.zip.
