I had this too:

> [16-Aug-2020 10:08:00 UTC] PHP Warning: Class ‘Tightenco\Collect\Support\LazyCollection’ not found in …/vendor/tightenco/collect/src/Collect/Support/alias.php on line 19  
> [16-Aug-2020 10:08:00 UTC] PHP Parse error: syntax error, unexpected ‘=’ in …/vendor/tightenco/collect/src/Collect/Support/LazyCollection.php on line 611

It was because MAUTIC requires PHP 7.2 and even though I had upgraded an htaccess setting had it at 7.0 still.

I also got a memory error after that was fixed:

[16-Aug-2020 10:53:07 UTC] PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 32768 bytes) in /home/jewishdata/public\_html/newsletter/app/bundles/LeadBundle/Model/CompanyModel.php on line 367  
[16-Aug-2020 10:53:07 UTC] PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 32768 bytes) in /home/jewishdata/public\_html/newsletter/vendor/psr/log/Psr/Log/LogLevel.php on line 1

Which we fixed by increasing the allotted memory via an ini file.
