Fatal Error – bug report

I cannot link to my page, since it’s in local development right now (thus I don’t need an IMMEDIATE fix, but I figured I should report the bug). I know this error has already been reported twice in the last few hours, but I figured I’d add what info I have (since it’s not in the other reports).

Running PHP 7.3.1, WordPress 5.5.1

No other plugins activated, using Twenty Twenty theme.

I activate Simple Calendar v3.1.32, and the back end of WordPress is fine (I’ll note that on the back end, when I turn on Query Monitor, there’s nothing reported). The front end, however, triggers a fatal error (I’m just c/ping the whole thing here for ease – probably more information than you need, but better to have too much than not enough):

Also from my PHP error log, which pretty much reflects the same, but may give a little more info:
