Comment (by pskli):

 Thanks for your help @oglekler

 My rewrite rules (fresh install, no other plugin except a custom one to
 load my custom CPT and taxonomy, see Gist above) are:
 https://gist.github.com/pierre-dekode/4ed610312680f7d6e67f56cf3b366081

 On PHP 7.4, I get a PHP Warning displayed on the 404 page:
 [[Image(https://p156.p1.n0.cdn.getcloudapp.com/items/DOulOdyk/a284f76f-
 04e9-4402-979b-ea2a9d3ed69a.jpg?v=20692802cdb05784aca6fbcfef01b762)]]

 On PHP 8.1, I get a PHP Fatal error:
 [[Image(https://p156.p1.n0.cdn.getcloudapp.com/items/o0uYnGlW/982102eb-
 42ec-44d1-bf28-fb0cca2c1803.jpg?v=ec663da301a9a599da8a6f30d7546124)]]

 ----

 If I install and activate Query Monitor, I can see that the matching
 rewrite rule for this URL is `'my_custom_post_type/?$' =>
 'index.php?post_type=my_custom_post_type'`
 The tested URL being
 `http://core.wp/my_custom_post_type/?my_taxonomy[]=test`



 Let me know how I can help!
