Just did a make update and getting this. How do I solve this?
C:\Program Files\TortoiseSVN\bin\svn.exe --non-interactive cleanup C:/blender-git/blender\..\lib\win64_vc15
svn: E155009: Failed to run the WC DB work queue associated with 'C:\blender-git\lib\win64_vc15', work item 36380 (file-install python/37/DLLs/_lzma.pyd 1 0 1 1)
svn: E720005: Can't move 'C:\blender-git\lib\win64_vc15\.svn\tmp\svn-E65722D0' to 'C:\blender-git\lib\win64_vc15\python\37\DLLs\_lzma.pyd': Access is denied.
I had a similar problem and the svn cleanup and svn update trick only got me so far until I encountered similar errors again. I ended up just going into the library subfolder where the error was occurring and deleting the files and then doing svn clean / svn update before trying make update again.
