Comment (by lifelightweb):

 I believe all of my servers have started having issues that are related to
 this bug report.  My servers are all on PHP8.1 and WordPress 6.6.2.  When
 there is more than 1 plugin that needs an update, the problems arise.

 The log file shows this:
 ------------

 Is there a work-around I can employ to get past this?
