Is Pr slow when installed on external drive

App version-25.5.0
Platform-Windows

Ok so recently i got new SSD 2TB one so I thought I will install Pr in my external 2TB SSD it might work well but something else happened so basically I have Pr Beta too which is installed on Internal SSD. While editing i start noticing app is opening so slow like 30 sec and Pr Beta which is on Internal SSD that app opens in 2 sec and in 1 click 

Later I fixed that by installing main Pr in my Internal SSD so I wanna know 
-Is this a bug ?
Because I have other app install on SSD they work well so I thought Pr will work fine too 

If its speed related thing (External SSD vs Internal SSD).Please let me know I just wanna know cause why this happening because people install games in External SSD they work fine so what thing is causing issue 

Extra Info
Pr is install in External SSD and Project file too are there in same SSD
After Opening I didn't face any crash or sudden freeze
