Getting PHP memory error

Thanks for your help in advance.
I am trying to upload several thousand topics to bbpress. I got about half way and now nothing happens. I can get to the last page when it shows the progress of the lines being installed and the topics being created, but i only see the moving bar and nothing happens.
I think it is having some sort of pho error with memory, but I have increased server pho memory to max and still same.
There is nothing blocking phop memory in user.ini or .htaccess files.
I’ve installed and re-installed the plugin. Change php version from 7.2 to 7.3, back to 7.1, and back and forth and still nada.
Reason I think it’s phop memory erros is because it did previously, and when I increased the php memory it worked for a few more files.
When I check server errors, I don’t see anything related to this plugin.
Any ideas?
