File names are no longer saving at full length

I do not want names truncated to fifty characters. If some users want filenames truncated, please add an option for max characters in a filename.

DESCRIPTION ==>> I updated to current version (v4.5.0.248/"most current version available", on Win10/x64/ENUS/mostcurrentupdates) a few days ago. Now i use it for the first time since update, and EVERY way i use it i get the same bug:
EVERY file i download from youtube gets its filename truncated to exactly 50 character length, exluding extension. I use SmartMode=Enabled, MP4-Video, Quality=Original, Subtitles=None, Directory=c:\testshortdirname"

REPRODUCE ==>> Take for example original URL https://www.youtube.com/watch?v=vA3QavPp1Ho, which should produce filename
"Joe Rogan Experience #1267 - Gary Taubes & Stephan Guyenet.mp4"
x) Copy URL to Clipboard, click "Paste Link" and start direct download. You get filename "Joe Rogan Experience #1267 - Gary Taubes & Stephan.mp4"
Thats EXACTLY 50 char filename (excl. extension)
x) Take playlist https://www.youtube.com/playlist?list=PLk1Sqn_f33KvXucAFMo5Tc5p8e_mcc-5g and "Download Playlist". You get for that video: "69. Joe Rogan Experience #1267 - Gary Taubes & Ste.mp4", exactly 50 chars, including the playlist-numbering(!)

PROBLEM ==>> SOMEWHERE in your code, the filename is truncated at exactly 50 chars. This is a NIGHTMARE when downloading long playlists, requiring to go through ALL files by hand, renaming correctly one by one - exactly the tedious repetitive work 4Kdownload set out to take off our hands. This bug creates just the problem 4K should squash!

REQUEST ==>> Thanks for the otherwise great software, but PLEASE fix this! Or tell me what i do wrong and how to get right results... I cant think that the behaviour described above is intended, at least without users being able to configure truncation!

Hello guys!
Please make sure you are using the latest 4.7 version of 4K Video Downloader - there isn't such an issue anymore.
