UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
It takes endless time to navigate in my folders each time i want to find my data files, something not happening at all in 1.083.4 (folders are opening fast). I have both versions installed on same laptop though. Both APP versions can be opened though.Â
I was never able to test the Ver2 Beta2 due to this huge delay in opening my data.
Thank you
The times I've seen this happen was when people had a network attached folder that wasn't available on the system. Is that the case for you?
@vincent-mod No it is a local SSD drive on a 16 CPU laptop with 32GB of RAM. Same files from the official version 1.083.4 works like a charm.
@teodigital Unfortunately the network drive doesn't necessarily have to be the location where the data are stored. The comment is much more generic: it can happen if there is ANY network drive that is not available. Is that the case?
Yes they are and your observation maybe correct. I can confirm that after removing network drives mappings Version 2 seems to work so i can do a few tests. Thank you so much for the accurate diagnosis of the problem.
