With the new update to 6.7.2, the usage of Mutlicell is showing Undefined Array key -1 error with php 8.1

Hi! We are using the php version 8.1 and before the update we were using the tcpdf verison 6.6.5 and it was working like a charm. Now after the update to 6.7.2 its giving exception. I am pasting the stack trace
[2024-03-20 11:54:01] local.ERROR: Undefined array key -1 {"exception":"[object] (ErrorException(code: 0): Undefined array key -1 at /var/www/html/vendor/tecnickcom/tcpdf/tcpdf.php:18829)
[stacktrace]

#4 /var/www/html/app/Exports/MonthlyBalancePdfExport.php(64): App\Exports\PdfGeneration->addBlankCell()
I am using MultiCell to create an empty row. But after the upgrade its not working.
Can you help with this? thank you :)
