FoF Upload can't be enabled. This issue seems to be very rare and isn't encountered by most of the other sites here in the community except of very few including mine.
The Extension able to be installed ✅ ;

But, can't be enabled ❌ ;

This is the same error that appears on both (Cli & Logs at /storage/logs) and even on debug enabled - same response, with no additional information.
This issue had been here ever since the first installation up to now. I had never had a chance to experience the extension until today 😅 .
Just that, previously i ignore the issue for meantime as there were some other errors being throwed due to some security restrictions at cdn and server-side followed by conflicts between the script (my flarum) itself with the server environment involving multiple aspects which had now been all resolved which i conclude as such as it resulted in no error generated since the last 30 days up to now and all extensions and core able to function ideally as per how it should.

Actions carried out to mitigate the issue;
Else than the encouraged php flarum migrate, php flarum assets:publish, php flarum cache:clear, i had also attempted;
1] Execute composer clear-cache, composer dump -autoload -o.
2] Removing certain potentially storing residual data folders manually - rm -rf storage/cache/*, rm -rf storage/views/*, rm -rf storage/tmp/*, rm -rf storage/sessions/*.
3] Clearing opcode cache via php -r 'opcache_reset();'.
4] Eliminating (Drop) the FoF Upload database table residues manually from the database tables.
5] Installing few older versions by manually stating the version during installation.
6] Dumping autoload manually to regenerate it specifically.
7] Creating missing tables manually.
Assuming the issue might only be with the initial table generation to enable and shall then work. Managed to enable the extension however it is not practical as even on every minor action table generation seem to be required.
8] Cross checking required php extensions, database operation permissions, file permission, memory and execution time limit.
9] Total cache flush for the entire account at origin and restarting the servers.
