error occurred directly after updating TYPO3 12.4.15 to TYPO3 12.4.16
but probably only once, now it doesn't occur anymore, I'll have to check again with the next update

Hey Bastian,
as this happened only once I am closing this issue. Feel free to open a new issue if this can be reproduced on a setup and is not related to e.g. switching versions and not clearing various caches.
I stumbled across the same problem. It always occurs once after a TYPO3 surf deployment was run for the affected project.
The reason was a missing JavaScript file that I tried to include in TypoScript:
page.includeJS.nonExistingFile = EXT:foo/Resources/Public/JavaScript/Build/config.js
TYPO3 tries to compress this file and calls GeneralUtility::getUrl for this path. As there is no such file, the getUrl method returns false, but then the ResourceCompressor tries to write false (bool) into a file in typo3temp/assets/compressed/external-abcdefgh12345678.
This is the call stack of PHP Xdebugger:
The solution for this problem in my case was quite simple: Don't include non-existing JavaScript files in TypoScript. 😉
