Hmmm. That’s strange that it shows this error.
I did some looking around and found these threads here:

The people having this problem seem to refer to database issues. (e.g. database is too large). After you uninstalled WordPress you removed your previous databases?
One guy suggested this:
Another potential issue could be related to the size and complexity of the imported data. If you’re importing a large amount of content with numerous attachments, the process might take longer, and a timeout could occur, resulting in the stuck import.
Another guy said:
I left the same database there, but:
a) Selected ALL tables
b) TRUNCATED all tables (the “Empty” option on the dropdown in PhpMyAdmin)Restored, and it FOR ONCE, did not hang at 95%.
Previously, I had tried with the existing database (which, in my case, with some plugins that were causing issues).
I also tried by renaming the database so the restoring one might work … no go.So I think that emptying out the tables to avoid my issue (duplicate index in PRIMARY) did the job.
I don’t know if these are relevant to your case. But, I’m not an expert on WordPress installation. I’m just searching around looking for answers. Other people have reported this issue with Softaculous and WordPress too. They seem to think it’s related to the database size or plugins. I don’t know. I’ve never encountered this before. Someone who knows more than me will have to chime in and help you troubleshoot this problem.
Did you read this FAQ here already?
