Component wont install correctly - missing table on Joomla 3.9.23

Hi,
installation leads to an empty page. Apache error.log shows "PHP Notice:  Undefined variable: main_menu in $website_path\\index.php on line 336" . After refreshing I got the message that table  XXX.#__eb_registrants is missing. However, Event Booking is showing up in the Components dropdown menu but dashboard doesnt appear displaying again the message that the table is missing. Other items like "Configuration" is working. It seems that the component was installed only partionally but without obvious reason.
I'm using Xampp, Joomla 3.9.23, Php Version 7.3.5.
Any ideas?

Hello Jacques

Look like there is not enough memory/execution time enough for Joomla to install the extension (it is quite large) and it causes the error

If it is on your local computer, you should change settings in php.ini to increase memory_limit and max_execution_time and re-install the extension

If it is on a public accessible server, you can submit a support ticket sending us super admin account, we will install and make sure it works for you

Hi Tuam,
thanks for your reply. My settings in php.ini are
max_input_time=600
max_execution_time=600
memory_limit=512M
upload_max_filesize=256M
post_max_size=512M
The values are accepted since var filesize is visible in joomla. Unfortunately I still get the same error - now without the blank page. Any other ideas?
Best,
Jacques

Update: I have made an online instance on the real webserver. Same issue. The installation failes with the same error message. I'm stuck now since I dont know the structure of the missing table.
