HELP! Can not load CTB file(about 4GB 20000layers) (ChituBox 1.7.0 and 1.93) into UVTools3.8.3

HELP! Can not load CTB file into UVTools!
Small *.CTB file examples are loading with success.
But, real large print file load process leads to ERRORS!
It contains about 4GB and about 20000 layers.
I try to generate it from ChituBox 1.7.0 and 1.93. (crypted and non-crypted)
At about 70% of progress bar indicator of loading i see the errors.
I tried to use 3.5.6 and 3.8.3 UVTools.
I checked it by ChituBox. It reloaded it from CTB to 3D-look back successfully.
I see no overloading of PC-AT Win10-64 RAM (64G) or HDD.

See the Errors:

4GB and about 20000 layers 😱

Thats way too much! What is your layer height?
Not impossible to load but that require a large amount of RAM on your machine, UVtools caches images on RAM, if you have not enough RAM such problems happens.

Will try to issue a patch.
Where i can get a patch? How to get it?

[sn4k3]

I think, You can get any STL with height about 20mm and slice it with 1mkm spacing.

Ok, i will try it.

Where i can get a patch? How to get it?

When I release next version, in two days maybe

Hello again!
How are You?
How about solution of this problem?

[sn4k3]

It's solved on latest version, please update

Ok. Many Thanks!!! New UVTools opened such big files and saved PNGs. Continue testing...

As to Exposure finder, One can propose for each Z layer to imagine all 30 squares for 0.5sec, then remaining 29 squares for 0.5sec... So, this would work faster in parallel in case of all 30 objects.
What do You think about it?

Another problem - how to shut off forced recalibration which occurs before printing and deathly sewn into firmware bosoms. May be You allready enountered with it? :

Detailed description:

1. I use extra-resolution resins with hardening depth about 20-30 micron only!
    
2. To use and print with this resins, I use Z-axle special support with spring, which, being unfixed with table, press table down with correct force, when resin is placed in quvette and support is mooving down into calibration marker and stop. Calibration position is done at this moment.
    
3. If i rigidly fix object table to z-axle support by knob turn and start print cycle immediately - i will achieve no first layer attached to table, because resin layer is still too thick.
    
4. About 10 minutes is required to squeeze out resin, forming thight contact between table and bottom of сuvette. Thickness of resin layer is diminishing with time from 0.5mm to 20mkm.
   (this velocities is not supported by forced calibration menu setup, and this is different for different resins, temperature...)
     
5. If i will use standart table where table is rigidly fixed on support constantly - i will crack LCD screen or Z axle motor will loose steps, because i use extreme rigid Z-Axle and LCD on thick quarz.
    
6. Time to time, I measure the distance between cuvette bottom and table (remained resin layer thickness), and when this value becomes less than 20-10 microns, I fixed table to support by special knob, and want to start printing.
    
   If recalibration will occur at this moment, i will crack LCD, or motor will loose steps, and, even will be ok wih LCD or motor - i do not achieve first layer attached to table.
    
7. I use this manual precise procedure because i use extra-resolution resins with hardening depth about 20-30micron only!
