Since the same symptoms came out, I asked if there was something in here, but is there still no solution?
I thought, but since I solved it with hint of sd 1976, I will leave a comment.
(It is my case to the last)
Looking at the log file, it was “Could not load file or assembly 'Newtonsoft.Json”
I thought that if I reinstalled “Newtonsoft.Json” it would be resolved, I attempted the following procedure.
(1) To install Newtonsoft.Json, either via NuGet or download source.
I tried the former.
(2) Download “NuGet.exe” from the website and enter the following command at the command prompt:
“Nuget install newtonsoft.json”
(↑ There might be a little lie)
(3) When downloading of something is completed and the console returns, close the command prompt.
When opening UiPath at this stage and checking the operation, two problems were both resolved.
I do not know if the other one has the same cause, so I do not know if it can be solved with the above,
I am fortunate if it helps.
