Contructor failed - 500 server error

Had a detailed explanation typed out, but apparently one can't have more than 60 characters in the title and.. here we are.

So the short version:

#1 - There's something funky with the code that checks the PHP version. Eventually got going with these (not sure which one/s are the right ones) PHP_PATH, PHP_CLI_VERSION, PHPPATH. Doesn't look like these suggestions from GitHub work: APP_PHP_PATH, APP_PHP_CLI_VERSION.

#2 - After trying installing both from git repo and zip package, keep running into these 500 server errors:

--
Constructor failed (View: /resources/views/common/dashboards/show.blade.php)
/vendor/akaunting/laravel-money/src/Money.php#594
--

LOG.warning: Return type of Balping\JsonRaw\Raw::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /vendor/balping/json-raw-encoder/src/Raw.php on line 5
LOG.emergency: Unable to create configured logger. Using emergency logger. {"exception":{}}
LOG.warning: explode(): Passing null to parameter #2 ($string) of type string is deprecated in /app/Traits/SearchString.php on line 25

Please let me know if i might be missing a step somewhere?
