looking at your error log from February, I think the crucial part is Fri Feb 18 21:14:58.430957 2022] [php:notice] [pid 49689] [client 192.168.1.1:64517] davical: BUG: :DAViCal Fatal Error: [0A000] SQLSTATE[0A000]: Feature not supported: 7 ERROR: set-returning functions are not allowed in CASE... This sounds like https://gitlab.com/davical-project/davical/-/issues/171 The important bit is to make sure that update-davical-database is run from the new package, and that it has replaced the expand_memberships function to not contain a CASE statement any more.
