Adobe Bridge 2020 crashes on starting in conflict with Tree Shade extension

I have developed Tree Shade extension and found that in Adobe Bridge v 9.1 there is no problem, but in the newest version the app crashes at this line

scopeInfo.push (scopeInfoFile.modified.getTime());

Also the scopeInfoFile is File object and the file exists. I checked that by writing info to a text file on Desktop
And I get this output:

scopeInfoFile instanceof File: true
scopeInfoFile.exists: true
scopeInfoFile.modified instanceof Date: false
