WordPress Timber/Twig: Failed to load Twig template, cache might be corrupted fatal error when upgrading to PHP 7.4.x

Question

I maintain a website on WordPress coded with Timber/Twig and ACF Blocks. Local installation runs on a Windows/Laragon with PHP 8 and is okay. Staging installation runs on a shared hosting A with PHP 7.4.x and is okay, too. Production however runs on a server B with PHP 7.2.x. When I try to upgrade to 7.4.x at least, I get a fatal error:

Fatal error: Uncaught Exception: Failed to load Twig template "templates/blocks/newsletter-form.twig", index "": cache might be corrupted in "templates/blocks/newsletter-form.twig".
in /www/[my_dir]/www/[my_domain]/public_html/wp-content/plugins/timber-library/vendor/twig/twig/src/Environment.php on line 502

The site is using Timber plugin for WP, version 1.22. I've been struggling with this issue for some time and run out of ideas. To my undertanding, it's not specifically a PHP issue, since both on local and staging installations I run exactly the same code on newer PHPs with no problems. (And yes, I know, that staging should theoretically be runned on the same hosting as production).

I tried to:

1. Remove templates/blocks/newsletter-form.twig template, but then the problem jumps further to page.twig
2. Clear caches with clear_cache_timber() and clear_cache_twig() methods
3. Reinstalling Timber plugin from scratch

None of the above worked. Obviously, keeping the website on PHP 7.2.x is not an option in the long run, so I need to solve this problem somehow.

Have any on you encountered a similar issue and found a working solution?
