Cursor stopped working GLIBCXX_3.4.30

I have the same problem, on Ubuntu 20.04.6 LTS as well.
Additionally I am experiencing the following problems:

  1. ctrl+click functionality on any function/component does not work at all.
  2. searching for strings/function names in my repo does not work well - it only returns results from files I have currently open.
  3. Saving a file takes a good 2-3 seconds as well.
  4. no suggestions/autocomplete pop up anymore

All of these happened after latest update.
